Working out who the baby dad is

[BreezyPearlSnail]

Hi guys,
have a very much dilemma on my hands - have posted before regarding the situation when I first found out.

Found I was pregnant back in April so went for a private clinic scan on 25th April and it measured at 7 weeks and then the 12 week scan on 30th may - measuring 12w1 (CRL 56.1mm) and had a follow up scan on the 5th June and measured 12w6 (with another CRL @ 64mm)

so here’s the story I slept with my ex towards end of February (28th) and then Again on 1/2nd of March - ( last period was 2nd February to 7/8th) I then had a suspected period on the 8th till the 12th - this was very on and off so to speak (I bled very similar with my currently 3yr old daughter if I remember and recall correctly) - now where things get difficult my own fault and actions I got drunk and also with a rebound one night stand at a party on the 22-23rd of March (don’t even know his name)

can you help me work out who’s it is? My ex is very much still in communication and has offered a dna at birth but we’ve both been asked online AI like chat gtp and deep seek and it’s giving us different answers each and every time

to note I do have PCOS

Thanks for the votes but what make you say ex’s the scans are confusing me

If the baby is measuring 12 weeks 6 days then it’s more likely to be from the one night stand. It’s been 11 weeks since 26 March so if your last period was a week and a bit before then then that would make it 12.5 weeks.

Yeah was 12w6 days last week on the 6th

People who voted ex probably didn’t read your post properly. Even at 12+6 on the 5th June, that takes you to the 13th March - which is around the time of your suspected period.

The good news is your ex is aware of the situation, which means it will be easy to get a DNA test.

good luck..

I agree with this. When dating pregnancy, they include the first two weeks when technically conception hasn't happened yet. So if you work back 10.5 weeks from 30th May, that put conception around 25th March? Equally, your 7w scan includes the two weeks prior to conception. So 5 weeks back from 25th April puts conception at around the weekend of 22nd March. As pp have said, its good your ex is happy to consider a dna test. You can also talk to your midwife in case there's any advice she can give you.

Correcting myself - 10weeks back from 30th May puts conception at 21st March, so very much in line with the 7w scan.

1st 2 weeks of pregnancy baby hasn't been conceived yet so that's putting you around 20th March for conception. So I would say it's the ONS (sorry op)

So no chance it could possibly be my ex’s

I’d put it as the ONS. Sorry if this isn’t the result you wanted.
