Possible late GD diagnosis 37 weeks

[C3PO31]

So basically I had a GTT at around 32 weeks because I was measuring 3 weeks ahead at a routine appointment, I was referred for a scan to check on baby’s measurements and then sent for a GTT as baby’s HC was above 97th centile and AC was above 95th centile.
This all came back normal so it was just determined that I was growing a whopper and I would be scheduled a delivery planning app with a consultant. ( for reference I myself am 5’3 and my partner is 5’7 and both slim so this was unexpected).
I had another midwife app at 36+4 which again triggered a growth scan as again I was measuring 3 weeks ahead, the growth scan tallied with my other measurements and again the AC was above 95th centile.
So they’ve referred me for a glucose monitor and a discussion with a diabetic nurse. I’m now 37+4 and due to receive my monitor today and I have a meeting with a consultant on Friday…
Am I being ridiculous in thinking that there’s no point now? They’ve faffed me about so much and I’m so fed up. My local trust guidelines are to induce GD pregnancies at 38 weeks which I am edging very close towards so they surely wouldn’t spring that on me on Friday the day before I turn 38 weeks would they?!
I am fully aware of the risks of a GD pregnancy and the potential for a large baby and difficulty delivering a large first baby/shoulder dystocia etc.

Has this happened to anyone else? What was the outcome?
Thankyou!

Just wanted to say that I'm in the exact same boat as you right now! Baby is on the 90th percentile. I'm awaiting the results from the test, but also worried about having to deliver a larger baby. I've actually booked a private growth scan as NHS scans are notoriously incorrect and a private one measures 3 times. Something to put my mind at rest anyway!

They can induce you ASAP with not much warning, my friends a midwife and told me they do it if someone is diagnosed late with GD. Pretty rubbish!!

Has your midwife spoken to you about birth options if you do have GD? Or if you don't, any options for not going past 40 weeks? Mine haven't been supportive or informative so hope you've had better luck!

I had a GD diagnosis at 38+ Weeks with Dc3. I had, had monthly ogtt tests up to 28 weeks as well due to my first pregnancy being GD but not my second which came back normal.
I had also had regular growth scans from 26 weeks as my previous babies were all very tiny. All scans were ok, and baby was growing and was small but my normal if that makes sense, I had concerns but was somewhat dismissed. The scans were performed by a consultant from 32 weeks. Then at a midwife appointment I was told I had GD from a test taken at 28 weeks as the trust guidelines had changed and pushed me over their threshold and I had to attend the clinic and receive my monitor etc, I was cross at this stage as I had voiced concerns throughout but not listened too. I went along at 38+5 weeks and for my dietary advice, monitor and then went for a consultant appointment for the GD afterwards. In my trust you have a midwife check BP etc prior to this, she measured my bump which she felt was a little small, then did a Doppler reading and was a little concerned as it was a little erratic. She disappeared, came back and took me for an immediate scan where it showed baby was measuring around 32 weeks but active but the cord flow was below normal. Consultant came and admitted me for induction with constant monitoring. However the Labour ward and maternity ward were full so I was monitored for a few hours, sent home with a slot booked for 8am the following day. Stressful night and an induction, Baby arrived at 39+4 weighing a tiny 4lbs 10oz, and on the 0.2 centile, she needed a little help with feeds and jaundice, but was ok. Turns out my placenta was failing and if it hadn’t been for a diligent midwife I am not sure I would of had the same outcome. I went on to have Dc4 with GD and an induction with little interference, I did refuse initially and explained my reasons. (Dc3’s birth wasn’t positive). With that the registrar, and on duty midwife discussed with me and we came to a compromise on birthing that accommodated my wishes and their safety concerns. After three DC’s I was insistent and wary of the care after dc3 though. You don’t have to be induced if you don’t want to, you can ask for more monitoring and to go to 40 weeks and reassess then. In all of my pregnancies induction has been pushed from early on, with Dc1 it was constant. Read the NICE guidelines and have a look on the Gestational diabetes U.K. page and Facebook page. They are very knowledgeable, supportive and helpful.

I had a similar experience in my first pregnancy. I was tested at 24 weeks due to familial risk, all came back fine. I was measuring ahead later in pregnancy and my daughter's abdominal measurements were over the 95th centile on a growth scan. They had me redo the GTT at 37 weeks, and my reading was literally the cut off for diagnosis. No one could decide whether that meant I should be diagnosed or not, said GTT can be unreliable that late, and though they talked about home monitoring, it never happened. I was induced at 39 weeks though, after 4 early sweeps. She was a 9lb whopper but super healthy.

I now have GD in my second pregnancy under a different hospital trust, and they're all a bit baffled as to why I wasn't diagnosed the first time. I can understand why it feels a bit late to be doing anything, but there are things they will do for you/ monitor during your labour to help keep your sugars stable, because that helps make sure baby is born with stable sugars. They also monitor babies blood sugar after birth for 36 hours I think? None of this happened for me or my little one because I didn't have a diagnosis.

Hi @C3PO31,
I'm in a very similar situation right now, tested negative for GD at 28 weeks. I'm now 35+5, had a scan yesterday (in my trust they are doing routine scans for research purposes but equally I had a low lying placenta at 20 weeks so would have been scanned anyway) which showed babies abdomen is very large and with all the other measurements has given baby an estimated current weight of 7lb 4!
I've got another GD test this morning but one I have to eat 50g carbs before a blood test 1.5hrs later. Not sure how accurate that is in comparison to the one I had before which was a blood test post fasting and another 2 hours after having a glucose drink.

I've got another scan scheduled in 3 weeks but that will bring me to 38+5. This concerns me that this is leaving it too late if they want to induce me early, similar to your trust at 38.
I completely understand the thought of what's the point so late on, I've decided after my test today I'm just going to be a bit more strict and put myself on a GD type of diet for the next few weeks.

It's a worry to think about the possibility of giving birth to a large baby, have they discussed this with you yet? So many people I've spoken to always say they can get scans wrong but that doesn't help my feelings very much!

Sorry I can't give any ongoing advise and can only empathise. I'm going to talk to my midwife today about that they might do if the GD test is negative but baby is still very big. Keep us updated to your outcome? X

It does seem a bit daft to diagnose you at this stage when you can't do much about it but it does affect your babies after care - they'll need to monitor their blood sugar once they are born to make sure they don't go too low. You can decline induction if you feel strongly about it - see what the monitor readings are saying, if your fasting levels are slightly above normal you might be ok to keep waiting but if they're very high induction might be best. Your consultant will help you decide.

So brief update,
I’ve got my glucose monitor and was advised to continue eating as normal and I would be receiving a phone call from a diabetes nurse next week.
So far all of my readings are distinctly normal, my fasting is around 4.3 and post meal is around 6.

My midwife is pushing for an induction, which I’m on board with depending on bishops scores etc! I do have a consultant meeting tomorrow to discuss delivery planning and apparently from friends experience she’s absolutely fantastic and actually listens to what you want rather than pushing her own views on you.
I’ll do another update post consultant review tomorrow, but fingers crossed she doesn’t want to induce this weekend…. I don’t think I’m ready 😳!

So I’m kind of in a similar situation. My baby’s AC has always been on the 95th percentile when I’ve had scans. I’m now 36 weeks and it’s hit the 97th percentile. They want me to do the GTT but they’ve not been concerned until now which is confusing because the growth pattern hasn’t changed at all. I’m booked in to be induced 39+5 so what will the difference be if I take the GTT. I personally don’t think I have it (I’m very slim and check my BS levels every now and then and they’re fine) I already eat relatively healthy so I’m not sure what to do. By the time they get me in for the GTT I’ll be 37 weeks. What do they do if it comes back positive for GD? Will they induce me earlier?
