TMI but I need help :(

For the past week, I thought I had a bruised cervix. So, I was okay with the small discomfort. But it started getting worse. I was feeling better yesterday and my boyfriend and I were going to have sex. I was all ready to go, and I went to sit down on his penis and he thrusted up gently, but it felt like I had literally been stabbed in my vagina. Stabbing pain throughout my vagina and my insides. I lost my breathe and started sobbing. It is miserable. What could this be?
