I am on my second pack of birth control pills after being on the Mirena for nearly a year. I had several problems with the IUD so I had it removed. I started taking my BC that following sunday and have missed a few pills here and there, Ive never taken pills so I wasnt aware that you could "catch up" However 2 or 3 weeks after my mirena removal. My fiance and I had intercourse and he did in fact finish inside me probably 3 times since. I started my period that pack. Maybe a week or so after that (not during the white pills, but maybe a week before the white pills, still on the blue. I continued to take the pack as normal. This next pack I am almost done with and "late" according to my last cycle , however i am not to my "placebo" pills quite yet. Lately I have been VERY tired even with plenty of rest, and even nauseated on some days. Last night after intercourse I became extremely light headed, hot, with some cramps and nausea. Took some Tylenol and the cramping subsided. Woke up again slightly nauseated, it comes and goes as of right now, i am slightly nauseated. Took a Ptest on 12/31 and was Negative, Since those symptoms have increased and worried i could be pregnant. Should i let the BC take course? or take another test? or What are the chances of me even being pregnant and this all in my head?
