Last Tuesday (3/24) my girlfriend missed her birth control pill for the first time ever and then took 2 the next day. We didn't have any sex until that Saturday after. Then this Wednesday (4/1) she took it 2 hours late and the next night we had sex and there was a brown discharge and it was there the next day too. Now today (4/4) she had slight bleeding. Her period is supposed to be scheduled in three days from today (4/7) should I be worried about the brown discharge or the bleeding today?
