I have been on birth control for two years, could that have something to do with it?
I would say you are ok but if you are still worried you can call your Dr. and ask for a blood test to make 100% sure.
i took a pregnany test on the morning of the day i was suppose to start a few hours before i started, and it was negative, should i be ok? thanks!
Yes you can have periods and still be pregnant. My mother did all through her pregnancy with me and my sister. But it's uncommon.
