Could I be pregnant or on my period AGAIN? I had intercourse on my 1st fertile day according to my period tracker and then the day following all unprotected, 2 days later i started bleeding a light red and then kind of dark, now day 2 of the bleeding it is very light and has almost completely gone away. I wouldn't think it would be my period cause I've been on it twice this month. I am also on the pill form of birth control, but I never take it at the exact time. Any input will help.
