Is it possible to measure behind early on and catch up?

[Lalarosex]

I am 100% of my dates as tracked ovulation with opks and bbt. Also only DTD once during fertile window.

Had heavy bleeding weeks 4-5. Assumed I had miscarriage but hcg kept rising. Had internal scan at 5 and 6 weeks - sonographer saw nothing both times. Was booked in for methotrexate and the consultant decided to hold off as my hcg was still rising. Started brown spotting which has continued since.
Had scan at week 7 and finally saw gestational sac with yolk in uterus. I have another scan at 8+3 and am hoping things are still progressing but have read nothing but negative stories about it being a certain loss if there’s no fetal pole/heartbeat by 7 weeks
Can anyone give me any positive stories?

My first measured 2 weeks behind. I found out the day period was due and had a 28 day cycle. I didn’t have any early scans but at the 12 week scan she was measuring only 10 weeks. Went back two weeks later and she was 12 weeks. Never caught up but I gave birth to a lovely little girl who’s now 12 years old. By the dates on the scan I conceived the same time i got my positive which was impossible. Never got an explanation but it was fine.

Thank you @PickledScrump thats great to know it all worked out for you wirh your daughter! I’m hoping for a similar outcome fingers crossed

I am exactly 2 weeks behind my period dates, albeit I wasn't tracking ovulation specifically, but I know my cycles and when we DTD.

I had a 'period' at week 4, exactly as expected, but it wasn't quite right so I did a test and it was positive. I went for a private scan immediately to be met with no signs of a pregnancy at all, I had to go back twice over a period of over 2 weeks before we finally found baby on a scan.

I'm currently now 22 weeks and currently all is fine. I should technically be 24 weeks going on LMP, but I've just tried to forget that now and stick with the dates I have and put it down as just one of those inexplicable things.

Fingers crossed for you.

Thank you and congratulations on your pregnancy! @DesTeeny it’s reassuring to hear another positive story. Do you mind me asking, when they were able to find your baby at 6 weeks was there an embryo yet or just a sac?

I measured 2 weeks behind when I was scanned at what should have been 7 and 9 weeks but by my 12 week scan, baby was only about 8 days behind

My son was a very scary pregnancy! He measured behind some weeks, above on other weeks and then he had blood in his bowels!

Other than this, he ended up being perfectly fine and was born 40+1. I know its hard but try not to worry too much!

They did find her the second time, well the sac, but there was no fetal pole/heartbeat, that's why I had to go back a third time!

So the first private scan there was nothing, second there was a sac but no visible baby, and third scan there was the fetal pole and a heartbeat.

They think I was only 3 and a bit weeks at the first scan, then 5 and a bit and then just over 6 when I went back the third time, but as I say, I should have been two weeks in front of that according to my dates. I knew my first scan would potentially be too early even if my dates were right but I couldn't wait to see if there was something there or not.

@FirstMondayInMay did you ever find out if your dates were off or just measuring small?

@Lalarosex I’ve still never found out! they think I just ovulated later than I usually would but that means I’d have got my first positive less than a week after ovulation🤔 I’m 26 weeks now and he’s stayed on roughly the same line, he must have just been a slow starter🤣

I had my scan today at 8w5d and since my last scan at 7w the sac has grown from 3mm to 10mm and a fetal pole measuring 2.5mm was now visible but no heartbeat yet. The sonographer said we want to hear heartbeat next but wouldn’t expect it of an embryo of 2.5mm. I am just baffled how I can be 100% certain of my dates, and be this behind yet it’s still progressing between each scan.

Both of mine measured two weeks behind, and I only had sex once each time so I'm absolutely sure of my dates!

Both were born pretty much exactly on my due dates that I worked out, according to my family history (42 week pregnancies).

Both healthy, normal sizes.

@VikingLady thats amazing, so good to hear a positive outcome. did you measure behind from early on?

From the flaming dating scan, where they tried to insist I'd hit my dates wrong and I must have somehow forgotten having sex. Nope. Not possible.

Anecdotally it's not particularly uncommon either.

But when they measured the bump towards the end of pregnancy there was so much variance in the measurements that they were almost meaningless. One appointment, I measured smaller than the fortnight before, so it isn't even remotely accurate.

Just thought I would update this thread incase anyone finds themselves in a similar situation later on.

After my scan which visualised the 2.5mm fetal pole, I had a repeat scan 2 weeks later when I had hoped to see it grow more. Unfortunately the sac was then empty and the pregnancy had stopped progressing.

I opted for a D&C which was done yesterday. In one way I am relieved as this was my first experience of pregnancy and it felt tainted from the beginning and overall a long emotional ordeal. We would have continued to worry the whole time had it carried on. Hoping for a positive smooth successful pregnancy experience soon!
All the best to mamas!

So sorry to hear of your update, be kind and gentle with yourself, it has been a real emotional rollercoaster, but as you say, here’s to a smooth pregnancy experience soon. 💐
