I need help!!! Who could the father be???

[Naomiisy]

I'm 28 weeks and 2 days pregnant now, but confused on who the father could be? Had sex with ex boyfriend the 17th of May and a different guy I was talking too the 21st and the 24th. The first day of my last period was May 11th, I was fertile the 20th through the 26th, and ovulated the 25th going by app. I'm saying the second guy is the father, but could it be my ex's baby possibly ???

When you had the earliest one, what number of weeks pregnant did it say you were (it might be labelled "GA") and what estimated due date did that earliest ultrasound give you?

[Naomiisy]

Yes I have had ultrasounds

[AnnieBrooke]

Have you had any ultrasounds at all during the pregnancy?  (The problem with computing from the first day of the last period is that it can be very imprecise, especially if your cycles are not like clockwork.)

[Naomiisy]

Using the first day of my last period, which was May 11th and my due date is February 15, 2015

[AnnieBrooke]

It all depends on how accurate your due date is.  Did it come from an early ultrasound?  Or was it computed forward just using the first day of your last period?
