Hi, well I've been taking birth control for months now & I didnt take it this past friday, or saturday. Me & my boyfriend had unprotected sex & he ejaculated, on Saturday. I took my birth control the following sunday & did not take it on the monday that followed. Sunday I had to use the the restroom & when I did i wiped, & saw some faint red blood. It was very light, not much at all. It then got heavier & as of now (Tuesday September 11th, 2012) it is still continuing. Is this normal? I even took a Pregnancy test monday & it came out negative. A little help? Im not quite sure what it is, or if i am pregnant.
