I have been taking Loestrin Fe1/20 for a month now. This guy and I have been having sex with a condom. I have only missed the pill once or twice and have taken it an hour later those nights I forgot. The thing is I had my period while I was on the third week of active pills. Is that normal? It lasted all that week. So instead of waiting to start my next pack of pills I started them right away. Well we decided to have sex without a condom but he pulled out. We both do not have any stds. How do I know for sure the bc is working correctly? Am I safe?
