So frightened I can't think properly :(

[Tollygunge]

Just posted this on pregnancy, which I now realise was prob wrong place.
I had a tfmr last year, at 17 weeks. Hardest thing I've ever done and feel like I barely survived it. The only thing that got me through was ARC and prayer. Am now pregnant again, and all seems well APART from the fact that at scans- and I've had several- baby consistently shows 7 days smaller than when I last had sex :( also, at start of pregnancy hcg wasn't completely doubling every 48 hours. I'm now convinced this baby has triploidy and am so scared. I can't stop crying. I have my NT scan tomorrow- will they be able to tell me? Has anyone else had an experience with scan dates being out that was positive? Should add previous prob wasn't triploidy.

Many congratulations on your pregnancy, I am sorry to hear it is full of worry and anxiety. Sorry I can't really help but I didnt want to read and run, hopefully someone will come along soon and reassure you x

I'm not sure what some of your anacronyms mean but its coming across that you are really scared about this pregnancy.
What's leaping out at !e is that you appear to be calculating the length of the pregnancy from the date you last had sex.
As far as I know, the calculation is made from the first day of your last period. Could this discrepancy in calculation account for the 7 days too small?
If this is a possibility, please go back to hopital\clinic\ gp and ask them to confirm.

Sorry, tfmr= termination for medical reasons. ARC are a support group for women hoping through this.

If I calculated from last period, it'd be 9 days too small :(

Should say though that the baby always grows as much as it's meant to- just those 7 days out

I am so sorry. I had a TFMR myself (first pregnancy) and it meant that in subsequent pregnancies I was just terrified for the whole 9 months and just expected something to go wrong (and of course it started off a whole new cycle of grieving each time). The chances are very good that everything is fine and you are just understandably very anxious. Try and be as kind and gentle with yourself as possible and make sure you have some support (do you have a good GP?). Is there anything you can do to distract yourself meanwhile?

I have lovely friends and family, so they're supporting me. It's strange, what you say about grieving. I can talk about my worries with this preg without crying but am still heartbroken every time I am required to mention termination. I'm not sure what I would do if NT is high- part of me thinks I will just get straight on to Marie stopes as we convinced ourselves before everything would be ok- harmony fine and then a bombshell at 16 weeks that she had Structural abnormalities incompatible with life

Poor you! I had a tfmr and I know that, if I do get pregnant again, I will be petrified of things going wrong.

I do think that it is likely to all be fine for you, though. If your baby has a low NT, then the chances are overwhelmingly good for you. If it would help you to feel better, the hospital may be willing to offer you a CVS which would give you more certainty. Or you could opt for a Harmony test - there's more info on that elsewhere on these boards.

I'm a bit confused, by your dates it sounds like you think you conceived two days after the first day of your last period? If so I think that's v unlikely, you are more likely to conceive at least ten days after your period starts, as that's when you ovulate. So it's more likely that the sperm hung around inside you till you you ovulated, meaning that the baby would measure smaller than you think it should.

Either way I think you will know for sure tomorrow at your scan

Good luck

Sorry, msbug, to clarify- last time I had sex was 8th august. Scans put conception at 15th august. According to LMP would have conceived 6th august, so either way there is something amiss.

Oh I see. Do you have long cycles? As they date based on an average cycle.

Either way there is plenty of hope. I had an early scan due to bleeding and was told that I was almost certainly miscarrying due to the foetus being too small and having no heartbeat, then a week later was told actually all was fine, she was just measuring a few days too small. She's nearly two now .

Cycles are irregular so not too worried re LMP, it's just that I know when we had sex and know small gestational suez indicator for triploidy

I can understand your worry, but ... you know you don't necessarily conceive when you had sex?

Sperm can live in the tubes for up to 5 days so maybe you conceived several days after sex with a long lived sperm.

Also it can take up to 7 days for the zygote to travel down the fallopian tubes and implant in the womb. So maybe yours just took longer than average to implant and that's why it didn't start growing till a few days later.

If growth carries on at a normal rate (i.e. you stay 7 days behind and it doesn't start increasing to 10, 15, 20 days behind) then I wouldn't be too worried... it is far more likely you just conceived/implanted a bit later than the date of sex, than that there is something wrong. Honestly.

How did your scan go?
