I ve been on micronor for a month, but was taking another mini pill before hand for about 12 months, I stopped taking it due to missing a weeks worth of pills about 6 weeks ago, I have had unprotected sex but have not had a period for 7 weeks, I took a pregnancy test about 3 weeks ago but came back as not pregnant, just wanted to know if it s normal for my periods to not have returned or should I be worried
