Pregnancy Scan / Date Discrepancy

I need a dose of realistic expectations, I think. I have had two MMCs and then a full term pregnancy that resulted in my gorgeous DD, less than a year old. I have just found out I'm pregnant again. I am suffering awfully with postnatal depression I think due to a really traumatic birth (ended in EMCS) and awful circumstances after birth with issues in the home (no DV or anything) but a house move, renovation and struggles in relationship, and relationships with extended family too.

Anyway. I did a clearblue test and got 3+ weeks, and an immediate very strong line on a normal test. I have been on edge with anxiety due to history and worry of repeat miscarriage so had a scan. From date of last period I should have been 8 + 5 but the scan has dated me at 6 + 2. They did see a baby and a strong heartbeat but did say that the discrepancy between the dates is very large.

It's not looking good, is it? This prengnancy was such a shock, I didn't realise because I am on strong medication for the anxiety and depression and my last period was end of September. I can't surely be that early? God, this is so hard.

Anyone at all? sad

You can be that early. You might have just ovulated late, especially if you are stressed. Are they having you back in a couple of weeks?

Pregnancy after a loss is hard to deal with mentally. Do you have anyone to talk things through with?

Hi OP, didn't want to read and run. Is it possible that you ovulated really late the month you conceived? That would explain the discrepancy in dates.

If you've seen a heartbeat, that's great news! Did the sonographer express any concern? Could you speak to your midwife about your concerns?

I really hope someone comes along soon who can alleviate your concerns, OP. Best of luck for a healthy pregnancy. thanks

I have my husband and my mum. There is also a mental health nurse / health visitor who sees me for my postnatal depression and anxiety who has been wonderful. The EPU want to put me through to a specialist midwife also. I can talk through things but I suppose I'm hoping someone will be able to come along and either assure me it's going to be ok or let me know it won't. No one can, I'm sure.

The sonographer didn't express particular concern, said the sac and baby were the right size compared to each other but that the date discrepancy is rather large 😢

I’ve had 3 pregnancies and my two successful ones have always been pushed back at the ‘12’ week scan - they plan it in based on your period dates and a standard 28 day cycle but mine mustn’t work like that. I’ve been put back my 3 & 4 weeks respectively.

I hope your next scan is consistent with your current dates

If there's a heartbeat, the embryo, the sac and the yolk are all good size, then it's all positive. Have you been tracking your ovulation? Have your cycles consistently been 28 with ovulation on Day 14?

JediStoleMyBike Tue 28-Nov-17 19:09:12

I've not tracked ovulation ever unfortunately, no. I have had 28 day cycles that were only irregular around the miscarriages. I have been on fluctuating medication of varying strengths and that has sent things a little off lately as well as the stress, I suppose. I suppose this could have been a period late September and then late ovulation due to my antidepressants being upped from 50 to 100mg? I worry I'm clutching at straws and just need to be realistic that this is going to go wrong. I desperately hope not though.

And sorry, they are getting me back to rescan in 10 days.

Hotpinkangel19 Tue 28-Nov-17 19:30:02

Ah, this happened to me OP. I went for a scan at 7+2, and was dated 4+4. Rescan a week later showed hb and sac. At the 12 week scan I measured over 13 weeks. I'm currently 34+3. Good luck xx

Well, maybe your dates a little off then. Good luck!

This happened to me!! Should have been 8ish weeks and had some bleeding. Scan said only 5+3 but with a heartbeat (which is highly irregular at that early gestation). They had me come back a couple of weeks later when by their calculation I would have been 7+3 but somehow it had all caught up with itself and the pregnancy was dated at 10weeks as I originally thought. Little under 7 months later lovely DD2 was born three days before what I had originally calculated as her due date. I don’t think it’s an exact science that early on.

My dates aren't off, as my last period came on the day I was moving house as I made a comment to my husband that the timing couldn't have been worse, offhandedly. I'm hoping that due to stress / medication I ovulated late.
Thank you for all the well wishes and luck. I appreciate the nice stories too, they give me a little room to hope that things will be ok 🙂
