First time and paranoid

Amy

I'm 18 and I had sex for the first time a few days ago with a condom I'm not on birth control yet and he said that he checked the condom after, but I'm super paranoid about being pregnant, I was bleeding after wards and my pee was cloudy today I peed after sex do you think I could have a uti? And do you think I should take a plan b or do you think I'm just paranoid?
