I just started birth control last Sunday at the start of my period. I usually have a pretty light flow throughout the week anyways, but this week there was a also a brown stringy fluid coming out as well. The first time i noticed that my period had started everything that came out was completely red. After several hours I took the birth control pill and that was when i noticed the brown stringy fluid. My period usually lasts about five days, this time it lasted six, and then today the pad I wore looked like i had pooped my pants. Do you have any idea what could be wrong, or if i could possibly pregnant?
