Hello, I have been takin Ocella birth control for over a year or two, and i sometimes skip the white sugar pills to skip a period. Usually when I do that, it goes back to normal within 2 to three days. Well even before the regular pills were finished, i started to get a cramping sensation in my stomach that made me believe my period was coming. I missed one day and started on my regular pack again. This was last thurday when i recieved the cramps. Now it is thursday of this week and i still have cramps. I took a pregnancy test that came out negative. The blood is not red, but a brownish color with thicker brown things that I think are blood clots. So i do not know if I had a miscarriage or a UTI. But I need help and an answer PLEASE
