Ovulation?: The pill works to supress ovulation as one way that it prevents pregnancy. In many cases, women still ovulate, and this can be associated with a small amount of midcycle breakthrough bleeding, cramping, and the usual pms like symptoms of bloating and breast tenderness.

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.
