Itchiness & Frequent Urination

Hello everyone! 
So ever since I ended my period (Monday, January 15th) I've noticed some itchiness and irritation in that area. At first I thought it might've been irritation from using tampons & that it would go away but a few days later I'm feeling like itchiness & irritation still. I've also noticed that after the itchiness on my clitoris, I have to pee really bad. I've never had this happen to me & im not too sure what it could be. I've only had one sexual partner my entire life & I've been his only. Has this happened to anyone else? If so, what was it & should I go to my Gyno?
