I am finishing my second pack of Trinessa. The first pack I got my period the first day of placebo pills. My boyfriend and I had protected sex the first month (as instructed). I take my pill at the same time every night give or take 20 minutes. We had unprotected sex for the first time just over two weeks ago. I'm trying not to stress but I really, really do not want to be pregnant. I have had cramps but that is the only pms symptom I've had. I have had a lot of stress and I am busy but other than that I am healthy. Any suggestions?
