Help ?

I’m due 30th October by dating scan and I slept with someone around the 10th of January and another person around 31st January …
what date most likely got me pregnant ?
I’ve had irregular periods due the last year before falling pregnant so my due date is by scan

The 31 Jan person more likely got you pregnant going by those dates.

If your periods are irregular I doubt it could be determined by date. You could seek advice from your midwife. I suppose it might help if you knew the date of your last period.

To work out approximate conception date, count back 38 weeks from your due date.

It's not exact as sperm can live inside of you up to 5 days before ovulation and dating can be off a few days either way but it'll give you a good indication.

You don't need to know your LMP once you have a due date from the scan as scan more accurate

Agreed. I also have very irregular periods, so had to date by scan. My first was due 25th September, and conception date was ~3rd January. So 10th Jan guy would be more likely to have a very early October due date, while 31st Jan guy would be late October.

While it's not impossible it could be the 10th Jan guy, scans at the 12 weeks are reasonably accurate. Not up to 3 weeks out anyway.

Thankyou my first dating scan I was 10 weeks 6 days so it would have been pretty accurate right ?

Definitely the 31st Jan

I ovulated 1st Jan & due 21st Sept. If it was the early Jan one you would be due very start of Oct

31st Jan.

I'm due on 5th October and my dates are roughly the earlier ones for you so it'll be the later experience!
