I m so confused. I thought I had a yeast infection so I bought some cream. But before I had a chance to use it my boyfriend and I had unprotected sex and when he cleaned himself it was brown(like leftover blood). And ever since I ve been bleeding rather heavily as if I m on my period. My boyfriend and I rarely have unprotected sex even though I am on the pill however I m not super regular about taking not. I usually forget until the next morning or take it an hour late or earl. So why am I bleeding and could I be pregnant???
