Hello, So Today I've Noticed Some Stinging In My Vagina,

Hello, so today I've noticed some stinging in my vagina, and I'm not sure if it's a yeast infection. I know it's not a UTI because that feels much different from what I'm feeling now. I just used some yeast infection cream and since I put it in, there is a burning sensation and the stinging is still acurring. The stinging only happens every 20 minutes and then it stops. Please help me.
