I am on the birth control pill Lo Loestrin Fe, I have been for about four months now. I take it everyday at 8 pm, sometimes a few minutes before or half an hour late. I had sex with my boyfriend on January 8th and since I am on the pill I allow him to finish inside me. A few days after that I started having this brown discharge/period with a few red spots but it was overall brown and it lasted well over a week. It ended on Saturday the 18th. My period is usually supposed to come once I start the sugar and iron pills, which is the last four of my pack and that is this week. I'm wondering if this is normal like breakthrough bleeding? Or should I be worried that I'm pregnant? And if it is breakthrough bleeding should I be expecting my usual period during the sugar and iron pills?
