Are you pregnant when instead of having your period you get mild brown discharge and cramps while you are on pills?

Not sure have you been taking your pills correctly??? I suggest that you take an at home test just to rule out pregnancy because if you are pregnant you need to be off your pills as soon as possible actually dont take them any more until you find out if your pregnant or not as they may cause birth defects....And just keep in mind that while you are on any type of Birth Control you can experience spotting or breakthrough bleeding in between periods hope this info helps, Good Luck and God Bless!!!!!!
