Hey I'm trying to find out when I ovulate and conceived my baby I had him feb 14th 2013 he was two days early my last period was may 12th 2012 but also I had sex with two men in one month one before my period witch was may 10th and the other may 16th and even after that date with second guy again but with my due date and last period online says I would have ovulated may 26th, but what happens if I ovulated before my period? Wouldn't my due date be different and changed so that's my question when did I ovulate could it of been before period and be the first guy?. guy that was on may 10th or guy that was may 16th and I no sperm can live for a week and those dates run into each other :( please help!

There is no way any of us can tell you that... really, there is no way anyone can tell you that. The only choice is to have a DNA test done to determine who the father is.

I'm sorry you are in this predicament, however you are going to have a DNA test done to determine paternity.

Is there a chance I got pregnant before my period or a few days after? Do u no

There is a chance either way. That isxwhy you need a DNA test.

Couldn't it of been figured out by ultrasound I had it at 12 weeks and wouldn't my due date be sooner then that if I ovulated before my period and if I did then means my Cycle was 24 and not 28

Gestational dating is all Best Guess based on available evidence.

No. It can't be figured out by ultrasound. Unless there is a camera in your fallopian tubes there is no way to tell exactly when you ovulated or conceived. DNA testing is the only way to know for certain.
