I have been on birth control for over three years now and have never missed a pill...until this past Friday. I usually take it between 9:00 and 10:00 pm every day, but for some reason, I shut off my phone alarm and then didn't take the pill and went to bed. I woke up Saturday morning and realized it so I took it at 10:30 am that morning and then went back on schedule with the next pill that night at 9:00 pm. as instructed. I was fine the rest of that day and fine all day the following day which was Sunday. Then Monday morning I woke up feeling absolutly nauseated and cramping. I figured it was because of the pills. But then, why was I fine on Sunday? And now it is Tuesday evening and I have been nauseated all day again. How long does it take for this to go away? I figured with just the one pill and then getting back on track right away it wouldnt be a big issue, now Im not so sure. I had my "period" for three or four days two weeks ago as usual and I was at the end of my second week in the pack when I missed it and we have not had sex since so I shouldnt be pregnant. The instructions even said I should not need backup pretection since it was only one and it was during the second week, but we will use extra protection just to be safe. I just want to know how long this ickiness is going to last?
