Im on the birth control patch and got my period 10-11days early. now im experiencing light cramping, clear discharge. could i be pregnant?

Check preg test: Breakthrough bleeding (bleeding at the wrong time) is very common 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. Discharge requires test.
