Hi. I NEED help! I had sex with two guys in a matter of a week apart. I'm not sure when exactly my last period was.. I had it in my phone as Jan. 9th 2013 that I was suppose to start. I can't remember if I did or not. I've been dating this guy for 4 years now(guy #1), and haven't gotten pregnant. I had sex with guy #1 a couple days before guy #2 and a week after guy#2. I had sex with guy #2 jan. 26th and 27th. Who's the father!!
