So my period came on September 5th. I had sex with guy #1 my ex boyfriend on September 14th but he DID NOT ejaculate in me, and we've been dating for some time. And has been having unprotected sex, and I have not gotten pregnant. I had sex with guy #2 which is my new boyfriend on September 17th and he DID ejaculate in me, and that was the only time. I went to the doctors and they said the day I conceived was September 19th and I'm expected to have my baby June 12. 2014. Which one is the father? Need help please!!!

It's more likely that it was the sex on September 17th, where you know for sure your boyfriend ejaculated inside you, but the sex on September 14th cannot be ruled out completely.
Sperm can live inside a woman's body for up to five days (some have suggested longer), and sperm can be present in pre-cum, so it is possible for either guy to be the father. The egg can be fertilized as soon as 30 minutes after sex, or as long as several days. You haven't given enough information to accurately determine when you ovulated, but since it's perfectly possible for sperm for the first guy to still have been living inside of you even on the 17th, or 19th, the day you ovulated isn't too important.
So, it's probably the second guy, who you had sex with on the 17th. It's pretty unlikely that it would be the guy you had sex with on the 14th, but it is still possible. (I am assuming that you are correct, and guy on the 14th did not ejaculate - if the guy on the 14th did ejaculate in you, then it's pretty much a 50/50 chance.)
