I took the pill next choice in September because I had unprotected sex, but it did give me a period twice in that month. So after that I had my regular period at the end of the month in October. But then I had unprotected sex again in November, but this time I didn't take the pill Next choice again, and I never had my period like I was suppose to in November and now it December. So i guess my question is does the pill next choice stay affect in my system after you take it, if not am I'm pregnancy?
