So i just started being on the pill on two weeks ago. I had taken a pregnancy test so i can acquire the pill as the doctor said.It came out negative, so i was not pregnant.That same day i had unprotected sex. Than as my chart said my period came 4 days later on time it started out really dark and then became normal red colour than 5 days later it finished but it is still brown. It also has little clots in it too, before and after when my period finished. I'm not sure if its just my period finishing or because of it being my first time on the pill.
