Could i still be pregnant?

I had my "period" for 3 months when I was pregnant. It was not my typical period but it was still bleeding nonetheless. You can bleed in the beginning of your pregnancy while the egg is implanting on the uterine wall. Don't worry too much because stress can cause problems for the pregnancy. I also didnt test positive on a pregnancy test for 13 weeks. If you're overly worried about it go see your dr they can give you better answers I'm sure.
