I have been on lutera birth control for about 8 months and I have not missed or been late on a pill for the last 3. Me and my boyfriend haven't been using condoms but he pulls out every time. I have gone through almost a whole pack of pills and have not yet gotten my period, is this normal? I think I remember my doctor telling me that it is possible to not get a period anymore but I don't remember. Is there a possibility I could be pregnant?
