Watery Discharge? Please help

So for a while I've had really watery, smelly discharge? like it feels almost like I've peed my pants. I have had to change my underwear multiple times a day and it just constantly feels wet down there.. I dont douche or anything like that. I'm a virgin and I'm not sexually active in any way. I'm 17. I'm not really sure what else to add. Its just so much and its getting really frustrating and embarrassing. Its been soaking through my underwear and onto my pants and no one else has noticed it but I feel like I can smell it when I sit. Should I go see a gyno?? If theres any info I'm leaving out that would be helpful, I'll answer! I just really need to make this stop.
