My boyfriend and i decided to have sex without a condom about 2 weeks ago. We had sex without one a total of three times; twice in one week and once the next. I am on Yaz, and have been taking it every night at 9 pm exactly. We have been very careful, and even though I'm on birth control, he pulled out every time--so he didn't cum in me.
Today, I'm supposed to start my period. Here it is 7 pm, and I don't even have any cramps, which is pretty odd for me. So naturally I'm freaking out, I guess because this is the first time I've ever had sex without a condom (even though we were still protected). So, someone relieve my anxiety and tell me the chances of me getting pregnant like this?
