My period was due to come on a Tuesday, but I had missed about 7 bc pills in this month and 7 last month. After I had sex with my husband, this past sunday, i started spotting orange blood. I had noticed that I had mucus in my stool (and the stool is green) about 2 weeks before this happened. Once Monday came, my period came and was pretty heavy, with lots of blood clots, and by Tuesday it was gone. Today he and I had sex again,and once we were finished, I noticed a big red spot in my panties. I took a pregnancy test which was negative... What is going on???? Can I still be pregnant?
