Have been taking birth control regularly for six years. About a month ago, after my period, I couldn't afford the next months pack of pills due to the loss of student health insurance. I wasn't able to get the next pack for three weeks. During this three week period I was having sex, but he was pulling out then twice he accidently came inside. I started my new pack anyway and I should have had a period after that 4th week, but I haven't. The only thing that confuses me is that I am on the birth control that you only have a period every three months, could the birth control have prevented the period after just a week and a half of restarting it, or should I be worried? :?:
