worried..

Bailey
so lately ive been having this weird feeling in my vagina.. and then all of a sudden it feels like i have to pee , but it doesn't really seem like pee because its not much at all, and then when its done its a bad burning sensation or like a cramp in my lower stomach, i had this happen to me once but it was only once and never happened again, this time it started one day then stopped and then these last two days its come back.. i looked online and it said this might be a UTI, is this right? please help
