I'm pregnant, who's the father

I have a very serious issue I'm faced with and I need a physicians expertise. I am 4 weeks pregnant as of Sunday November 13, 2011. I had sexual intercourse Saturday night, October 29, 2011 and before day in the morning around 1:30 a.m on Monday October 31, 2011 with someone else. The fertility calculators all say I conceived October 30, 2011. Would guy #1 or guy #2 more likely be the father? The first day of my last cycle is 10/16/11. Please help to enlighten me if you can.

Absolutely no way of telling without a DNA test. Sperm can live inside you for up to 7 days.

Sperm can live inside a woman for up to 7 days so its almost impossible to tell the exact date you concieved. With the occurances so close to together the only way to tell will be a DNA test. Congrats and good luck

Well both those dates are too close to go by an estimated calculator...you will have to get a paternity test after baby is born to know for sure... sorry this really is the only way to know

Agree with the other ladies.  Absolutely no way to tell other than a DNA test.  Just way too close.

Those dates are way too close together to tell. I believe your only option is a paternity test.

Get a paternity test once the baby is born.
