Hi I'm a 17 year old female, and lately I've been noticing I have almost all the symptoms of a uti. I'd like to point out, I am sexually active. One day I woke up with this pain like cramps, but it didn't go away for 2 hours. I started doing a little research and it said to drink plenty of water, so I've been doing that for 3 days. I go pee a lot, like every ten minutes. Is this good? Do I have anything I need to be worried about? Do I have to go to the doctor?
