I've been on birth control for a year now and I have had no problems. I would get my period on the exact day I was supposed to every month. No cramping or anything. I stopped taking it after my pills ran out at the beginning of March. I got my period and finished it on March 8th. I have yet to get another one since then. I am sexually active (same person for 3 years) and we use condoms while using the pill. Does this sound like just an effect from the birth control? I also should add that I once missed a few pills (when I first started taking it) and got my period after I missed 4 days. My boyfriend and I did break a condom on March 12th but got a new one before continuing. I'm currently finishing up my undergrad and will be graduating in the middle of May. I'm used to being under stress so the added stress is nothing new. Should I be concerned?
