My LMp was December 10 2009 and I had relations with my boyfriend somewhere between December 16-22.. I met a guy and had a one night stand one morning between 3am and 5am on December 25. I am now preganat with a little girl and I'm due September 17. I'm so scared and confussed about this situation. I really need help and some answers, I am not sure if my little girl is my boyfriends or the one night stand! Please help!!
