I have been on birth control for about a year, but for the past week I have missed 4 pills and have either ended up taking them the day after or within a few hours of when I m supposed to take them. I had sex without a condom on the 16th, me period was due to start the next day. I understand it is not likely to get pregnant this close to your period, but it does happen to a lot of people. My period did end up starting on the 17th, but it stopped completely already and it is only the 18th. Does it sound likely that I could be pregnant?
