I am really unsure as to what is going on. This month I started birth control, a combination pill, I had sex on day 4 of taking the pill, so I took a plan b the next day. Then continued taking birth control the next day, on day 8 I had sex and he didn't ejaculate. Then I had sex again and he cam inside me barely, and one more time we had sex but he pulled out, and I take my birth control every morning. Last Monday I started to have light spotting, that turned to heavy the next day (I thought I got my period), but day after that it was light, then that night started up again. But then after that it was light and turned to brown, and now it is 9 days since the bleeding started and still have brown spotting. Did I ovulate this month or no? Am I pregnant? Or light period ?! Please help me I'm going crazy googling, can't do it anymore.
