Help I'm in pain

I need some help I just had intercourse with a man who was very well endowed like 10 inches and he was thick (sorry about the grafics). Now I'm a skinny girl and I didn't think that his penis would make me feel like I'm in so much pain. I need to know if I should see a doctor because it feels like I'm on my. And I'm having light cramps and the size of my vagina is big and it hurts when I pee it's like an orgasm when I use the bathroom. Can anybody help me with what I need to do because from what I noticed warm water helps the cramps and I just took 800 milligrams of ibuprofen and I took one pamprin. Please help😭😭😭😭😭😭😭😭😭
