I've been on the pill for 4 months now. I missed the first pill of my current pack but took it the next morning (2 pills one day). I always get my "period" on the Wednesday of the inactive pills (Sunday being the first day of inactive pills). I did get brown discharge on Wednesday but Thursday it was very very light & not much blood through out the day. Is this normal? I also had unprotected sex but waited a week after I missed the pill.
