I am 19. I was on one type of Birth control for about 3 years when my doctor decided to switch it. I had the first month of it and everything went normal, but now into my second month I had about a week of heavy brown bleeding a week before my period was due. I have been off my birth control for about 3 days now and still no period. Me and my boyfriend are sexually active. Will I still get my period? Does this have to do with a different birth control? Could I be pregnant? I'm just really not sure what this means so if anyone could help it would be appreciated! Thanks
