I'm 21 yrs. old and had a baby last year who is now a year old. I got an abortion once after I found out I was pregnant again. I bleed every month and not once had a bleeding between my period. But 2 days ago, when I went to the bathroom I noticed that I was bleeding lightly. I still am bleeding and I don't understand why. The smell is different (iron like smell). Also, when I have intercourse with my boyfriend, it hurts. And for some reason, I don't know why my cervix hurts when he hits it. I'm really worried... What could it be?
