I'm worried I might have a UTI. I'm sexually active but always make sure to pee after sex and had sex last night. Today I had a tickling feeling when I peed but it didn't burn or hurt and I also feel like I have to pee more than usual. I'm visiting my boyfriend who lives out of state so I don't have a doctor here and will be here all week. Is there anything I can do at home since its early on?
