Bleeding only when i pee then wipe..brownish reddish, going on for a month now. im on bc for 7 months.skipped the sugar pills for 12 weeks.what wrong?

Breakthrough bleed: Breakthrough bleeding (bleeding at the wrong time) is very normal on birth control. It happens in about 1/3 of users. Its no big deal and usually self corrects over time. If you are not satisfied or it continues to happen then consider using a different birth control method. It is a common side effect and does not mean something is wrong or that the pill is not working.
