I have been on the pill for a little less than a year now and never miss a day and always take it at about the same time everyday. About a month ago my boyfriend and I had sex but didn't use a condom. Since this is the first time I have ever had sex without using a condom, I am making myself very paranoid. He did not even ejaculate at all though..but it still worries me. I had my period about two weeks afterwards and have been feeling pretty normal. Do I have any reason at all to worry about pregnancy?
