Someone please help I started withdrawal bleeding this week and my cramps were so bad I couldn’t even go to school. I had a giant blood clot with tissue in it which I search up and it appeared to be a decidual cast I don’t know if I’m typing that right but it’s something like that. Basically I think my uterus tried to shed itself all in one go which didn’t work because I’ve still been heavy bleeding. I didn’t tell my parents about the giant blood clot. I took my birth control religiously on time all this month and I never missed a day still I’m worried because this morning after all this crazy stuff is happening I threw up. I’m hoping it’s just what I ate the night before not agreeing with me. Can somebody help me to know if I should be scared or not. Either way talking to an adult is not an option.
