Pregnancy Concerns: Determining Father & Gestation - Expert Advice

Question
I had my last period on June 6, I gave up my virginity June 28 to my best friend, I had a pregnancy test done on June 30 it was negative. I then had sex with someone else the first week of July, I just found out I'm pregnant, but who is the dad and how far long am I - please help.

Answer
Angie,
If you are positive of your dates, you probably conceived between June 13-20. You would be due March 14 and are 8 weeks pregnant today. Are you sure of your last period? You should make an appointment with a doctor. Ultimately you will need to have a paternity test done to figure out who the father is. Good luck.
