... issues wirh weight gain and moods so I have switched a handful of times. I was on lutera for a couple years and had few issues til the past year so I was switched to microgestin 1/20 the one without 4th week pills. I finished the pack a week ago and still haven't gotten my period. I have had unprotected sex a couple of times but have done nothing different than I had with any other pills and never even had a scare. Should I be concerned it has not arrived yet? I seem to be reading this is coming during the switch to this pill
