I'm on a 3 month regimen of Mononessa (21active pills, skipping the placebos of 2 packs). I have taken one pack already and two days after starting the second pack, I had unprotected sex and the next day I forgot to take a pill. The next day I took the missed pill with the one for that day. It has now been a week where I have taken every pill on time since. Could I be pregnant?
