When did I conceive

[babymamalol]

Okay pls don't judge but i need to know!
My LMP was March 10th 2013, I am 31weeks & 1day pregnant right now with the due date of December 15, 2013 (so the doctor told me) then the ultrasound tech tells me December 17? But the real question is since I conceived late March sometime, I was intimate on the 23 with my ex then a week after on the the 30th with my current bf who's baby would it mostly likely be? Help help help!!

Most likely your ex but it could also be your bf  if you have irregular periods

I guess I'd say a lot depends on how early or late in your pregnancy the ultrasounds were.  If they were early, they are more reliable for dating purposes than if they were later.  Conception calculator says:

     First day of last menstrual period:  March 10
     Probable date of ovulation:  March 24
     Possible dates of conception:  March 20 to 28
     Due date:  December 15 (40 weeks)

If your ultrasounds were farther along in your pregnancy, both guys could be in the running.  If they were in your sixth to eighth week or something like that, then the guy on the 23rd has a pretty strong edge over the guy on the 30th.

I also think it's you exs baby because I have the im expecting app on my phone and I put in you LMP and it said that you conceived on the.24th

I think its your ex, if u have normal ovulation on the 14th day of your cycle then u most likely ovulated around 24th so I think its your ex's baby
