On Saturday, my boyfriend and I had unprotected, rough sex. It was his first time and my first time in 6 months. It was very lubricated. The night we had sex, when I got home, I went to the bathroom to pee. My left vaginal lip was extremely swollen and painful. The next day, Sunday, I woke up, and it didn't feel any better, but the swelling went down a TINY bit. When I've been using the bathroom, there's an odor. Today, Monday, the swelling went down another tiny bit, but the pain has no change. When I went to the bathroom today, I peed and right after I peed, I felt so empty. I sat on the toilet for a moment and I started to feel something coming out of me and it felt like period blood, but I am positive that it was not period blood. (Im sorry that this is gross) I stood up immediately, and looked down and it was some liquid, as thick as period blood. It was dark brown and yellowish-greenish. I took toilet paper, and got the liquid and flushed it. Please help

I would go to the doctor as soon as possible. I don't know what happened or what that fluid was but something ain't right. It could have been him too rough or maybe it wasn't his "first time" and his "last time" gave him a STI.

It is something that is serious enough that I would go see a doctor about it.

I agree with Craven. Something like this I think does merit a visit to the doctor.
