I think that unless something in the way you are recounting the dates is mistaken, you conceived around May 23.
So in other words there's no way the guy that I had protected sex with could be the father? Also want to add the condom did not break, and it was also the last day of my period...
Given a due date of February 13, you would have conceived on or around May 23. Most of the evidence does add up to the second guy. The only reason that might be incorrect is if the February 13 due date is way off, but it's hard to see that it would be as far off as it would need to be to implicate the guy with whom you had the protected sex.
I didn't have an ultrasound until July 23rd... They told me my due date was February 13, they gave me that due date based on the wheel and the ultra sound
And did you have any early ultrasounds? If so, did it give you an estimated due date based on the measurements of the embryo?
I'm saying with two different guys
Are you saying the protected sex was with one guy and the unprotected sex was with another guy? (Because, why would it be driving you so crazy if it was all with the same guy?) Anyway, did you have any ultrasounds in July? If so, did they give you an estimated due date based on the measurements of the embryo? You can use that EDD (if it is from an early ultrasound) and pretty accurately assess whether you conceived on or around the 21st.
Most likely when you were ovulating.
