Hi, I'm a 17 year old female. I have just gotten my period on the 15th January. It came 4 days early. For the past two weeks I have been peeing frequently. In 30mins I would have gone to the toilet at least 4 to 5 times. I get this tingly feeling but when I go to the toilet I pee very little. I am indeed sexually active. I had unprotected sex on the 3rd of January but before then too. I've been sick lately but this frequent peeing has been annoying. What is wrong with me? Do I have a UTI? Because the other day which only happened once, I had a burning feeling while peeing.
