About last week I missed 4 pills and I didn't get my period for missing the pill and just this week I missed 3 pills and got my period and at first coming out red and now it is coming out brown? But about a week and a half ago I had unprotected sex with my boyfriend and thought the reason for not getting my period the first time for missing the pill was because I might be pregnant but this time I'm not sure if I am or not. When I usually get my period it is not red not to mention for the last 2 weeks I have been getting pain in the abdomen, headaches and lower back pain. What should I do? And what does it mean?

Hmmm well how long have you been on the pill... normally after taking the pill for so long your body adapts to it and would be a little harder to just get pregnant. The reason for the change in schedule of you menstral is most likely because you missed you pills and then took pills. But if you say it is brown could be a bladder infection. You should definelty so see the doc just to make sure.

Wonder if anyone can help me. I missed my pill for a few days and have had sexual intercoure so because I was at the end of my month of my pill a week later I stopped to have my period but never had it. Could I become pregnant?

Something similar is happening with me,, I had unprotected sex about 9 times in 4 days, then I lost my pills and missed 6 of them, I am now bleeding however its not as heavy as my normal period and its watery, can I be pregnant?
