I am currently taking Lutera birthcontrol pills. I am very god about taking them every day. I always go two months before having a period because I tend to get very bad cramps. Im on my last week of pills before my period and Im experiencing brown discharge. My boyfriend and I are very careful and we always use a condom on top of my normal birth control. Should I be worried this spotting is a sign of pregnancy or is it just from taking the birth control pills?
