Kinda Scared...

So I just recently had some pretty rough sex with my SO tonight and it’s been a while since we had last had sex (literally 2 weeks is too long for a period to last...anyways...besides the point). We’ve gotten pretty rough before but I’ve never had any discomfort afterwards. I’m always left pleasured and happy. But tonight was different. While we were having sex...it didn’t feel uncomfortable at all. Nothing hurt and it felt fine. Then afterwards (maybe like an hour or so later) I had to go to the bathroom and it stung like crazy. It hurt. 😭 I talked to my mom about this and she said it was totally normal and told me to take some Advil and to also take a hot bath to ease the pain. Well then I had to pee just a couple minutes ago and it STILL hurts!!! 😭 Btw she had told me to take Advil and a bath around like 9:30-10ish and it’s 1:37 rn. Now I would say I’m a pretty healthy person...my boyfriend was my first and I was his first so we’re both clean and everything (STD Wise...) What if it still burns tomorrow?? What should I do? We’ve been rough before but it’s never affected me like this until now. Please help. (Sorry for the long story. I hope it wasn’t too TMI.)
