Did I Break My Hymen?

The other night my boyfriend and I were having sex, and this was just my third time having sex ever. It was a bit more rough I guess due to how many times we changed positions, but he ended up getting very deep inside me, deeper than he’s ever been, and that’s when I felt a sort of pinch. A while later, after we turned the lights back on, we saw that there was kind of a lot of blood. He thought it was because he was too rough, but I think it might have been my hymen breaking. I wear tampons a lot, so I figured it was already broken. I just don’t understand that if it was my hymen, why it didn’t break the other two times we’ve had sex. Was it because he’s never been that deep? The day after, I was more sore than the first couple of times we did it. What happened? It wasn’t because I wasn’t wet enough, because along with me being wet, we used lube.
