I started birth control a month and a half ago. Me and my boyfriend had unprotected sex for two weeks, I was taking my pill perfectly the entire time, exact time and everything. However, I begin to get an extremely irregular period that lasted about 2 weeks (normally have 5 day long periods). So I stopped taking that birth control for 3 days of of fear! We had sex last on Thursday the 25th of June at about 8 p.m the last birth control pill I took was on Sunday the 28th of June, (those three days after we had sex last, I took the pill perfectly). I missed, Mon the 29th, tues the 30th, and weds the 1st and on Thursday took 2 pills, and started taking them regularly again. My concern is that I may be pregnant, because sperm can survive inside me for 5 consecutive days. We did not have any sex at all after the 25th. Is it extremely likely I am pregnant?
