I'm in a huge mess and I'm really ashamed of it... I have a boyfriend and we always have unpretected sex because we are trying to have a baby well I can't remember the exact day I got my period but I'm thinking it was around the 21st of may 2010 on Friday the 28th I had unpretected sex with my ex.. twice the first time we finished and the second time he didn't.. after he left my house I used the restroom and I remembering having a lot of discharge during the day. I then went to my boyfriends house and I hade sex with him the same day and many days after that as well I just found out I am pregnant last night I think I am 5 or 6 weeks pregnant and that's just a guess.. I am really lost and would like help if anyone knows anything about this pregnancy stuff I would appriciate it a lot.

There is no way at all to be that exact. So there is no way at all to tell which one is the father till after the child is born and you use a DNA test

IF the first day of your LMP was May 21, most likely you conceived on or around June 4. Now this is just an estimate. It is impossible to tell for certain exactly when you conceived.

If you did have sex with your ex on the 28th it is possible that he is the father. Only a DNA test done after the baby is born will determine parentage.

Wow. Nothing awesomeness about this situation.

DNA is the only way. I hope for all four of you, you get the test done. Be sure to see a doctor and start taking prenatals ASAP. Best of luck to you.
