Who is the father

[Killakrew]

I had sex on my period march 23 with man A and had sex with man B April 2nd and 6th  my LMP was march 20th my due date is January 2nd

I had a sonogram on may 10th which put me at 6weeks and 1 day

Who is the dad?

[Killakrew]

That' makes me so happy thank you

I apologize for not noticing in your original post that you mentioned April 2 and 6.  Man B fits the bill, Man A is far too early.

I'd look at the April 6 person as the strongest possibility for dad, unless there was also a different person anywhere after the 1st of April.

Yes that sonogram gave me the due date January 2nd the last time I had sex was April 6th

Well, and this is important -- did you get the projected due date from the same ultrasound that gave you the 6w1d figure?

The reason I ask is that for a due date of January 2, the conception calculator gives the following:

Probable date of ovulation:  April 11
Possible dates of conception:  April 7 to 15

... and you don't mention any sex as late as April 7-15.
