Ok I posted this earlier but never got any really good advice. Me- Unprotected sex with a lady friend November 30th 2009. She- Her due date just jumped like 2 weeks to August 10th 2010. It was the end of July before this so I never really worried about being the dad, but now it got jumped way up... so it kinda makes me wonder now. She has a boyfriend so its not like I was the only guy involved with her at the time. Also: When she first went to the doctor when she found out she was pregnant the doctor said she probably conceived at the end of October based upon how old he said the fetus was.. well then how come now the due date got jumped up? Was the doctor incorrect at calculating the fetal age at the beginning? I am sick to my stomach and cant believe this might be happening, I grew up in a good home and now might have a child who wont have their real parents together. I know the only way to know for sure is a paternity test but i need some opinions on these dates. I would try to make it work with this girl if it was mine but she already has a boyfriend, and he knows nothing about any other guy bein with his girl. If its mine I want to know though so i can be there for the kid.
