Constantly peeing

I’m 19 and on Friday went for a drive with a guy for a few hours. I hadn’t drank any water but had 2 large coffees. I had to pee really bad but couldn’t cause we were driving. After when I was driving home I didn’t make it and peed myself! Ever since i keep feeling like I have to constantly pee. Idk if I’m paranoid from it or have a problem. I feel fine but just don’t feel relieved for long after I pee and have been peeing like 15 times a day. What do I do. I’m also a hypochondriac so idk if it’s me doing this to myself or an actual problem. I’m worried.
