I'm 16 years old, and lately received anal from my boyfriend. It wasn't the first time but it was the second, the first time I didn't feel sick afterwards, just stomachache. But this time it was different, when he tried to put it in I had this really bad burning feeling down there, anyways I'm afraid I might be pregnant, we haven't done anything from front yet my hymen is safe (I think), but ever since last night I've been having weird bowel movements and nausea. I'm afraid it might have somehow slid down there, and he did rub his penis in to my vagina but didn't come in me. Afterwards I farted something watterish and red? Guessing it was cum and blood. Please help, I can't tell my family about this and where I'm from abortion is illegal and shy to speak to my boyfriend.
