UTI question?

Hey guys, so I've seen a lot of people posting about uti's and then I saw that one person's uti turned out to be a cyst. The only symptom I have is that I have to go to the bathroom A LOT. This has been going on for a few weeks. After I use the bathroom, I feel like I need to pee 5-10 minutes later, and there's a good amount that comes out. My bladder area is slightly swollen too. Occasionally I'll feel a sharp crampy pain that starts on the right side next to my vulva and then travels up my pelvis area to right next to my hip bone. The pain only lasts a few seconds and I don't feel it that often, but I do need to pee a crazy amount of times in a day. Like I probably peed 3 times in the last hour. However I drink a lot of water so idk if that's why. Any ideas as to what's going on? Thanks.
