Im 19 and I was on Loestrin 24 fe for almost 3 years. I have been with my boyfriend for 5 years and decided to go off of the BCP because of the symptoms. My last brown pill (placebo pill) I believe was on Jan 5-7. I really can't remember. A few days later we had sex but he put it in once and then we used a condom after that. I am not sure if it is normal to miss your period after stopping the pill. But it is really annoying not knowing when I am going to get my period. I also took 4 pregnancy tests and they were all negative. I become very paranoid about this as you can tell. Could I have gotten pregnant from that one penetration?
