I am 26 years old.So while on my period my man cums inside of me (no big deal) on my third day,im still bleeding enough to where i know its my cycle, well this time round he came in me on my fourth day as well , well for this time i used a planB pill..so im thinking i took care of it. Why is it that three days later im using the bathroom at work and i notice a good amount of blood to where i know im not on my period still, i mean it just came out of me ,out of no where so now im checking myself like crazy. Whats the best advice someone can give me? Should i be worried or is this a effect of the pill i took?
