Constant urge to pee

21 F for the past 2 weeke I feel like I have to pee way before I actually have to and it’s uncomfortable, there is no pain. Dr. suspected UTI put me on medicine for five days and nothing changed this also started after I accidentally used a un unclean vibrator. I’m not sure if it’s related but it’s starting to scare me and drive me insane because I don’t know what it is and it’s very uncomfortable. There is no pain when using the bathroom just the constant feeling like I have to go. Anybody else have the same issue?
