Measuring MASSIVE for dates - help!!

(42 Posts)
LePamplemousseMousse Mon 29-Jul-13 13:24:01

Just come back from MW appointment and according to fundal height I am measuring four weeks ahead for dates! I am 27 weeks and measuring 31. Apparently this is, quote, "off the charts". Until now baby has been bang on from all measures and scans, so it's a bit of a shock.

She wants me to go for a scan today if they can fit me in, which has freaked me out as there's usually such a long wait. I asked her if it could mean there's a problem with the baby and she deliberately didn't answer the question - just told me to go ASAP, but it's probably just the way the baby is lying.

I am not overweight (right in the middle of the BMI chart before PG and gained about a stone in pregnancy so far, if that), eat a healthy diet, don't have diabetes or any kind of history, so I'm a bit worried what it might mean. My first baby measured perfectly all the way through and was a normal weight at full term, just under eight pounds.

Any one else had any experience of being very big for dates? What was the outcome?

mustardtomango Mon 29-Jul-13 13:39:00

I had the same, though not quite to the same degree - measuring 2-3 weeks larger thank he should. The midwives did an extra scan where several of them had a go at measuring his head /torso etc, and the outcomes they offered were:
A) my dates were out
B) he was just huge
C) I may have gestational diabetes

They've decided in the end it was B, though spent some time deliberating.

I'm sure its just precautionary, I'm now surely if scans area wholey reliable anyway. If need be, this justice gives them the chance to look after you better.

Good luck! X

I had the opposite problem with dd, I measured tiny and found it very stressful with extra growth scans etc. she was born 6lb 12oz so while not huge not tiny either. I think I worried constantly about it for the last month of my pregnancy.

My advice would be to go for the scans but to try and stay relaxed about the whole thing

tabbycat7 Mon 29-Jul-13 13:53:12

My midwife said the same to me and sent me off for a scan. They measured ds4 and said he was fine, he'd probably be 7-8 lb. He was 8lb 16! But he was 10 days late and I had no trouble getting him out. A friend of mine was also told she waa huge, had a scan, they told her baby would be 10lb. He was 7.5.

It could be lots of things, maybe just how the baby's lying, or how much fluid there is or how you are carrying him. smile

LePamplemousseMousse Mon 29-Jul-13 14:45:20

Thanks ladies, I feel a bit better now. I guess I'm panicking as a friend's SIL was measuring very large all the way through, and lets just say the outcome was not good. They hadn't taken the size of the baby very seriously in spite of her concerns.

I spoke to the midwife again just now (couldn't get a scan today as she'd requested so wanted to ask her what I should do), and she said she wants me to do it in the next two days 'in case there are any problems and we need to get you to the hospital'. She still wouldn't say what she meant though! Gah!

AnythingNotEverything Mon 29-Jul-13 14:49:53

I went to hospital last week to be monitored due to decreased foetal movement (all fine now!) and was measured at 30 weeks despite only being 27. Midwife wasn't at all concerned, although I am pretty tall and DC1 was over 9lb.

Seems odd that they weren't concerned about me but your midwife is panicking you! I was a divested that as long as measurements follow the curve of the growth chart, the actual size of your bump doesn't mean much. Maybe with first babies its different.

I'd try get an answer out of your midwife, but enjoy the opportunity of an extra scan!

FoofFighter Mon 29-Jul-13 14:51:12

Sh'es probably thinking either gestational diabetes or too much fluid.

Rather hmm of her to worry you like this without actually saying much I feel.

Measuring 6 Weeks ahead here have a scan tomorrow x

LePamplemousseMousse Mon 29-Jul-13 14:59:56

Thanks Foof that's what I thought. It's unlikely I have GD to be honest (normal weight, don't have a sweet tooth, no family history), so I'm worrying about excess fluid now. I'm sure she's just trying not to freak me out but I told her I'd worried myself by Googling and she still wouldn't talk about it.

Anything apparently being four weeks over is more of a concern than two or three. I'm trying to focus on the fact he was a normal size at the 21 week scan (middle of the centile chart). I am worried that fluid could have accumulated in the last six weeks though.

I told myself I wasn't going to freak out about this, and now I'm panicking sad

LePamplemousseMousse Mon 29-Jul-13 15:01:16

Good luck falcon let us know how you get on xx

valiumredhead Mon 29-Jul-13 15:10:07

Try not to panicbrew thanks thanks

valiumredhead Mon 29-Jul-13 15:10:42

Oooo over zealous with the flowersgrin

FoofFighter Mon 29-Jul-13 15:11:03

GD can appear out of the blue regardless of family history and your weight and it's def not because of sweet tooth wink

When have you managed to get in to be seen? (and why isn't your MW arranging that for you??)

Carolra Mon 29-Jul-13 15:11:52

I had polyhydramnios (too much fluid) from weeks 27-38, I was measuring 3-5 weeks ahead depending on which midwife took the measurement. I had a lot of scans and had to do the glucose test twice, they were convinced it was Gestational Diabetes, but it wasn't... just one of those things apparently.

By the end of week 38, I was measuring back to normal, and ended up having a natural birth, dd was 7lbs 8oz and arrived 40+5.

I found having the extra scans quite comforting, it was good to see the baby and know she was developing as normal. It did hang over me for the last couple of months though, knowing that there was something unexplained going on but I was happy to have whatever tests they wanted.

mistlethrush Mon 29-Jul-13 15:17:26

My midwife wasn't at all helpful with the scares. She diagnosed extra fluid at one check and then left me terrified for a week as I had an appointment at the hospital already booked for them - I ended up speaking to a friend who is in the business and said that it was complete tosh that she was talking about (turned out it was tosh).

She also sent me for a GD test - the consultant spoke to me and measured and told me I didn't have it - but that I'd have to do the test anyway just for good practise...

She also gave me a preeclampsia leaflet and told me to read it through carefully 'as she expected to see me in with it in the next few weeks'.


DS was born a week early at 10lbs 5 oz...

LePamplemousseMousse Mon 29-Jul-13 15:17:38

Thanks valium grin

That's interesting foof! I think MW did the GD test at this appointment (took two sets of bloods) so hopefully I'll know soon. I am pretty tired but only very recently, until two weeks ago I had boundless energy, but maybe that doesn't mean anything.

Carolra that's reassuring, thank you, so glad it all worked out well for you and your DD. Did they suggest a reason for the excess fluid?

LePamplemousseMousse Mon 29-Jul-13 15:19:13

Foof first scan they could do is this Thurs so not too long to wait. No idea why she doesn't book them - didn't in the last pregnancy either even for routine scans, and it was a bit of a stress!

LePamplemousseMousse Mon 29-Jul-13 15:24:57

Oh God mistle the pre-eclampsia leaflet, how awful! I'd have been in pieces! So glad it all worked out well - what a whopper grin

pinkr Mon 29-Jul-13 15:25:04

Don't worry...I measured 40 at 32 Weeks. Turns out I have excecss fluid from gestational diabetes. Now we know i've got it we are monitoring my blood levels etc and now at nearly 37 Weeks I'm still measuring the same...I figure this means the baby is growing but the fluid is decreasing. I get another scan on thurs.

pinkr Mon 29-Jul-13 15:28:29

Oh and I have none of the markers for gd...no family history, in no way over weight etc. these things just happen sometimes

ratbagcatbag Mon 29-Jul-13 15:33:51

I measured 2-3 weeks ahead the whole way through, had a scan at 32 weeks due to decreased movements, they estimated baby was 7lb already. Sweepstake at work guesses were in the 10lb plus range bastards I ended up having dd at 37+4 (waters went so induced) at the humongous size of 6lb 12oz. I had gallons of fluid though, waters went whilst sitting on DH side of the bed, it absolutely flooded everywhere. smile

Wickedgirl Mon 29-Jul-13 15:38:20

I measured 4cm too big with my second baby. I had an extra scan at 34 weeks and everything was fine. Gave birth 10 days early to a boy of 9lb 13oz. He is now almost 13 and is very slim. I am slim myself so a big baby was a surprise but I had a natural delivery using only gas and air

Good luck

PoppyAmex Mon 29-Jul-13 15:41:20

"I had polyhydramnios (too much fluid) from weeks 27-38, I was measuring 3-5 weeks ahead"

Same here, DD was 10lbs 8oz, freakishly long and perfectly healthy.

Freudianslap Mon 29-Jul-13 15:42:20

I was in a similar situation a few weeks ago, measuring MASSIVE, sent for an urgent scan that day. Was totally terrified....
But had the scan and baby was measuring absolutely fine, the sonographer said (very tactfully) that the midwife had possibly measured incorrectly but also said that te fundal height is affected by loads of simple things like the baby lying on its side etc.

Hope all goes well xx

DialsMavis Mon 29-Jul-13 15:43:33

I measured big with DD2, they kept doing the glucose test and got me in for an extra scan. I read up that they always say the baby will be huge and they end up being 7lbers.... DD was 10lb 2oz <winces in memory<. She is now a very tall but very skinny 2 year old.

flipflump Mon 29-Jul-13 15:47:54

The test is not done by blood tests, so you may still be asked to go for one. I was measuring 2 weeks over according to midwife. Scan confirmed baby was big but measuring one week over. Excess fluid can be a sign of gestational diabetes. If you have got it it's no reflection on a sweet tooth etc. Don't worry, you'll be treated accordingly and on Thursday you will have a better idea of what's happening.

gamerchick Mon 29-Jul-13 15:49:09

I had polyhydramnios as well.. Measured 4 weeks ahead right till the end. Breaking the waters was great fun.

He was 7lb 8 and physically healthy.

Sometimes its just one of those things.. Extra scans and gd tests.

Try not to worry.

MissStrawberry Mon 29-Jul-13 15:58:24

You could have polyhydromnious.

You need to keep a close eye on the baby's movements and go to be checked if there is any change or you can't get any response from the Baby.

I had this with DC1 at 38 weeks.

Carolra Mon 29-Jul-13 16:14:49

They never got to the bottom of it, it just went away... We'd hired a doula who was amazing and really reassuring throughout the whole thing. She told me that bump measurements are just a guide and a lot depends on who is doing them, the scans did show an increase in fluid around the baby but no reason for it. When she was born she was in the 50th percentile for all measurements. I still secretly think it was all because I ate too much cake. grin

FoofFighter Mon 29-Jul-13 16:29:46

Yep the GD test isn't a blood test but an oral glucose test.

LePamplemousseMousse Mon 29-Jul-13 16:38:15

I am now starting to wonder about GD. I've always felt a bit funny after I've eaten anything really sweet (I can't drink orange juice without watering down with 50% water or I'll feel really sick, for example), hence not having a sweet tooth. I had really bad morning sickness for a while, and the only thing that helped was carbs and sweets - very, very unlike me. No more morning sickness now, but I'm still drinking things like ribena which I'd never have had pre-pregnancy and a lot more carbs (which I kept to a minimum before too). Work are constantly plying me with biscuits and cakes too (which again, I never normally eat) - I joked last week they were going to give me GD. Doesn't sound so funny now hmm

pinkr Mon 29-Jul-13 18:36:15

Nothing 'gives' you gd...certainly not anything you eat, its to do with hormones etc. however if you do have it then cakes etc will not be good for your sugar levels.
I don't eat much sweets etc anyway...one of the things I was told to cut back on was milk...I was drinking pints and its high in natural sugar!
The test is that you fast over night, they take blood, give you a sugar drink and then take more blood two hours after.

TarkaTheOtter Mon 29-Jul-13 20:37:55

Agree with pinkr, whilst bmi is a risk factor for gd it isn't "caused" by diet, it's hormonal. It also doesn't have symptoms so don't stress out looking for them. You'd know if you'd had the gd test (called gtt). You fast overnight first, then have bloods taken, then drink a glucose solution, then two hours later another blood test.

I'd have thought if she was that worried about gd she would have booked you in at the hospital for a gtt. They are done every morning round here.

Fundal height measurement is very inaccurate. I had two midwives measure me in the same day and the difference was three cm.

LePamplemousseMousse Tue 30-Jul-13 08:29:57

Thanks pinkr and tarka for the info - just have to wait for the scan on Thurs now and hope it's all a storm in a teacup!

gamerchick Tue 30-Jul-13 10:59:54

If they send you for the gtt, take a book. It's a long boring thing.

Meid Tue 30-Jul-13 11:08:57

I also had polyhydramnios. Like others diagnosed at about 28 weeks and I was measuring 4 or 5 weeks ahead right until the very end.
I was a bit frightened as I was told the baby could come early (as my body might think the baby is due before it actually is) but in the end I was induced at 41 weeks. The worst part was feeling very uncomfortable.
You'll probably have to do a test for GD which takes a good few boring hours of your time.
All the best.

curiousgeorgie Tue 30-Jul-13 11:26:32

My friend was measuring huge for dates, everytime she got scanned or measured the weeks jumped up even more and she was expecting a 10 - 11lb baby and terrified..

He was 7.5lbs! They're not always right smile

MissStrawberry Tue 30-Jul-13 14:00:32

True. I was told I was having an 8-9lb baby. He was born 4 hours later weighing 6lb 12.5oz.

LePamplemousseMousse Thu 01-Aug-13 15:37:16

Hi all. Thought I'd just update.

Had the scan and apparently everything is in normal ranges. They don't even want me to do a GTT. Phew.

Three midwives have now measured the fundal height and all three put me at four weeks over. Having seen the scan they don't have an explanation. Perhaps being as it's my second baby I just have no tummy muscles left at all wink

Thanks for all your advice and reassurance. Feel like I can relax a bit now. Phew.

ChunkyPickle Thu 01-Aug-13 15:44:35

I measure bigger at afternoon appointments than at first thing in the morning ones. As the day progresses my bump gets harder, and pokes up higher (I can add on 2 cm just by tensing!)

Plus, I'm sorry, but I really think that they are over-estimating the accuracy of a midwife, a bit of prodding, and a dressmaking tape!

Razzdazz Thu 01-Aug-13 16:31:56

Glad all has worked out well for you OP grin.
I was measured by my consultant yesterday a whopping 12 weeks ahead shock so I'm 30 but measuring 42!! I do have GD and polyhydramious so they have booked me in for a section at 36 weeks if I make it that far, steroid injections in the next 2 weeks.

Razzdazz wow!

I had my scan and she is measuring 4 weeks bigger but they don't think it GD as i have normal fluid levels she is just a big baby smile

Glad all is good op smile
