Meant to be 8w5, measured 5w5

[Ceramic272]

Hoping someone can help me make sense of these dates/recent scan :/

Last period started 13/14 June; I have a long cycle (33 days or so).
The CB ovulation tests were not working properly that month so I’m not sure of the exact date. Cheap Amazon tests showed a very mild surge on 1 July (though still comparatively very low); gave up on testing after that. Only DTD that weekend and 8/9 July though so conception has got to be around one of those weekends.

Measured 2-3 weeks pregnant on clear blue on 25/26 July.

So by today I’m meant to be 8w5 (counting back from 13 June ie first day of last period). I started light brown bleeding yesterday so booked in a private scan today as was convinced it was the start of a mc. Went and the sonographer said I’m only measuring 5w5, and too early to even check for a heartbeat. She said she thought I’d probably just ovulated very late in my last cycle, and to come back in 2 weeks to check if it’s reached the expected size then. She didn’t think the brown blood meant a mc either (as it’s not heavy red/clots).

She didn’t seem worried but I’m so confused and still pretty worried. Is this normal?? I assumed the scans accounted for the extra 2ish weeks at the start (presumably no one is getting pregnant on their period)..how can I be 3 weeks off and that be normal? I’m worried that maybe it just stopped developing at some point :/. Please reassure me that I just am misunderstanding all these week measurements…

Actually I meant I measured 2-3 weeks pregnant on the clear blue test on 1/2 August (not 25/26 July).. tbh I had just assumed that the timing was wrong, but maybe that matches what the sonographer was saying..

I'd you conceived Saturday 3rd/ Sunday 4th then that would put ur measurements at the right size from conception. I'm measuring 8w 3d my LMP was 17th June. I find it all very confusing.

Why not give ur EPAU a call and explain what's going on.

2-3 weeks on the clear blue tests is actually 4-5 weeks as they don’t count from your last period whilst pregnancy weeks do. So if you were 4-5 weeks on 1/2 august that would make you 6-7 weeks now, so not so much out on dates. It’s possible you ovulated later, and it’s possible it’s a mc. Unfortunately at this stage you can’t tell and it could go either way. Have they booked you in for a rescan?

Going by LMP is only useful for those that have regular 28 day cycles and ovulate around day 14. For anyone else it can cause worry when you’re not what you expect ar a scan.

For both my pregnancies I’ve measured 7-10 days behind what they expect because I ovulate around cd21-23. Try to carry on as normal and go for another scan in a week or two, it’s rubbish but there really is nothing you can do right now but wait.

Scans do add on the two weeks before conception. It’s entirely possible that you ovulated late and you actually conceived 8/9th July weekend which would make sense for your dates. Unfortunately it might be a mc too, there really is no way to tell at this point. Have you contacted epu as you’ve had some bleeding?

Was it in an internal or abdominal scan?

Thanks all. They did both abdominal and internal scans. I guess even if I conceived on or after 8/9 July, presumably the scan still should’ve been around 7 weeks (if they add on 2 weeks) so it still feels quite off. But the sonographer just didn’t seem that worried at all, which threw me as I couldn’t see how this could be ok. They’ve booked me in for a rescan in 2 weeks.

I haven’t called EPU as I naively assumed they wouldn’t be open on the weekend.. I’ll try them first thing tomorrow. Hopefully they can do a more definitive scan..:/

I just really wanted an answer either way, this thread isn’t making me feel hugely positive.. (no slight against anyone, I really appreciate the input, it’s just validating my concerns!)

@Ceramic272 im sorry it’s not been much help. For what it’s worth at my first 12 week scan she was measuring 2 weeks behind at only 10 weeks, which was impossible as it would have meant I conceived the same time I got my positive test. She’s now 12 years old. I never got an explanation of why she was 2 weeks behind and she never lost or gained any for the rest of the pregnancy, so not necessarily bad.

I suppose it also depends on when you implanted? Implantation can take up to 12 days so could be a delay there I would think. Also remember the size they are measuring right now is millimeters. It's easy to be a few days or even weeks out as the difference is tiny in size. Fingers crossed for a good outcome

I called my EPU and they also seemed concerned about the weeks being so off, but unfortunately (like the private place) there’s nothing they can do at the moment other than book me in for a rescan in 2 weeks :/. So I guess I just need to wait it out and try to stay positive..

I conceived on 09th July and I'm 6+1 today if that helps? Implanted 8DPO if BBT is accurate based on one day dip. Maybe it was too early to get an accurate reading hence 5+5?

So.. I called EPU and they said I could have a scan today if I wanted, although they weren’t sure if it would show anything more than the private one. I decided to go in as I was bleeding more and wanted to see if the private scan had really been accurate. EPU said I was showing at 6 weeks with a heartbeat (albeit a low one)- which private one hadn’t detected-and that they weren’t concerned by the bleeding as it wasn’t that heavy, and basically said come back next week and see how it’s progressing. They didn’t seem bothered by the dates either tbh.

That gave me some hope.. but I’ve now started cramping and just passed a large red clot, so feel like I’m back to square one. Ugh.

It’s very frustrating how the scans can’t really tell :/. I think I have to assume at this point that I have/will miscarry, but the uncertainty of everything is what’s driving me nuts.. I feel like I’m just waiting to see whether I’ll start gushing blood or not. Like emotionally I’m pragmatic and “ok” (I get miscarriages are very common, it’s fine) but the lack of clarity on everything / up and down of this has thrown me so much :(. Can’t focus at all and don’t know how to handle it with work either - how can I know whether to take time off if I don’t even know when/whether I’m miscarrying etc?! (work in a very male heavy / hardcore group so definitely not something I can share at all with people) :(

Sorry to hear your going through this @Ceramic272 there really is little support for women suffering early miscarriage. Hoping for the best outcome for you💖

Thank you <3. It did end up a mc in the end, and the hospital confirmed it. Felt oddly relieved, I’d known my body wasn’t right for days and getting the false hope made it worse. So it was a relief to just have a definitive answer and move on. Obviously it was pretty unpleasant (ended up in hospital with a lot of pain) but I felt levelheaded about it and trying to be positive going forwards. Treating myself in the meantime with a lot of coffee(!)... Thanks all for the support and wise sounding boards

So sorry for your loss, OP

I'm sorry for your loss @Ceramic272 💐
