When did I get pregnant?

I am 17 weeks and 5 days as of 3-23-08, from my last period. My last period was nov. 22. I cheated on my boyfriend and slept with one other guy on the 30th of nov. Is it possible that the baby could be the other guys? Or is it exactly 2 weeks after your last period that you get pregnet? Thanks and please respond soon

the baby coud be any of thoses guys!!
Becoming pregnant and your due date and how far gone you are is calculated from your last period but it could be either of the guys!!

Yes, because you had sex with both of them, so there is a possiblity that it can be either man's. :] good luck.
