I am on the pill but I have missed one here and there in the 9 months i have been taking it but always take it the next day. I have had unprotected sex with my fiancee but I have been having what i think as periods. I sometimes have them 2 times a month or just he regular once a month. We do have 3 children already and it doesnt feel like when i was pregnant with them but then I wasnt taking the pill. I was just wondering if there is any way I could be pregnant and if the pill could be causing me to bleed like I am having a period.
