know who the father of my baby is

Hi Trish,

When did you have sex with the two men?

If your period started around 8/3 then you would likely ovulate between about 8/14 to 8/19.  Sperm can survive about 5 days and your egg about 48 hours so having sex from 8/9 to 8/21 could result in pregnancy.

Now the bad news.  You don't conceive immediately after you've had sex.  Either man could be the father.  You will likely need a DNA test.
