Hi i think i have thrush, no discharge or smell. just very itchy at the entrance. also stings a little when i pee. i have also noticed small dark purp?

Sounds like yeast: Vaginal itching, without discharge or odor, is typical for yeast infection (thrush). Stinging urine also is common. It is a common but mistaken belief that yeast causes foul odor. It can cause scant vaginal discharge but often nonet. See a doctor to confirm diagnosis and Rx. Or try an OTC yeast treatment (any product with active ingredient ending with "azole") and see MD if it doesn't help.
