I've been on birth control (pill) the past 2 years and I just started a new packet after skipping the placebo pills (I was with my boyfriend, didn't want my period) for last month. I have my period now and have wicked cramps, I went to the bathroom and literally a chunk of my uterus lining (I think) came out, it was the size of my hand and all red, and kinda skin color with spots. Could it have just been the lining or possibly my body pushing out a miscarriage? We had sex twice unprotected but with me being on the pill. This has never happened before...help, please!
