Hoping a doctor/sonographer/radiographer can help..

[31weeksgone]

I have to get this all out and I can’t seem to make it make sense to anyone, so please bear with me.

I have polycystic ovaries, and ovulate (if I do) very very late in my cycle.

I am currently very newly pregnant.

My last period was the 9th of January.
I believe I ovulated around the 28th, ish.

I got my first VERY faint positive test on the 4th of feb, presuming I’d of been 7DPO then.

So I’ve had a few scans (due to recurrent miscarriage, and needing progesterone) and currently last Thursday the sonographer and doctor put me at 5w2d since conception, when going from my last period I should of been around 7weeks.

I tried to say to them, I was worried about how far along I was, and should I be adding the two weeks (from last missed period, the 14 days you’re not pregnant for but is included) to this, and I would actually be the 7 weeks I thought I was.

They’re insistent I’m 5w2D from CONCEPTION (would be 6 weeks today by now) so would I actually be 7weeks ish, and I can stop panicking that I’m so far behind, or are they including the 2 extra weeks too? I did say all of this to them, but they didn’t quite get me.

I’ve got another scan in 2 weeks when I’ll be 7w2d from conception, and by my calculations I’d be “9-ish weeks from LMP” if you get me. The first scan I was 4ish weeks with sac, 2nd scan I had a yolk sac and 3rd scan I had teeny tiny 5w2d measuring embryo luckily with what looked like a heartbeat.

Apart from acne and slightly sore boobs, I’m symptom free for now which is obviously concerning.

Can anyone understand what I’m trying to get at? Or do I just sound crazy?

Thanks for bearing with. I know I just have to wait it out, but years of time and money have got us to this stage, so obviously it’s very worrying and precious.

Bumping to see if anyone can help at all 👀

I have no medical experience but yes from your first positive at 7dpo you’d be 7 weeks, surely they always add on those extra 2 weeks rather than from conception? How fustrating they didn’t seem to get your concern that you’re 2 weeks behind!

No medical experience here but conception is definitely just after you ovulate so you would be right in adding the 2 weeks to this. I’ve never had any sonographer date from conception before. Well I guess they do but add on the 2 weeks automatically and not mention it.

It’s never usually dated from conception.

id say if there was a fetal pole with FHMs seen then it’s more towards 6/40, which would fit with your late ovulation. When they say 6/40 it’s from first day of last period.

it’s all pretty approximate on very early pregnancy, just the general appearance is in keeping with a 4/5/6 week pregnancy. Guidelines are not to date before 8/40 when it is more accurate. It sounds like your scans have followed on and progressed nicely from one another. Once there’s a decent CRL to give you a gestation to work with then you can use that to assess growth throughout pregnancy, so hopefully this will be reassuring for you.

It all sounds very normal to me so far and I would just go with the flow and wait for an approximate EDD by CRL.

Sorry, I feel asleep after a super long day. Thanks everyone for your opinions, I guess I’ll just have to wait it out until the next scan. Thank you.

Yeah they always go from last period until your 12 week scan then the measure and confirm I went to my 12 week thinking I was 12 and 1 but she measured 12 and 5. I am in the final hurdle now 7 weeks left 🙀
