No I don’t think you are having an STD. I think you are experiencing the symptoms of UTI (urinary tract infection). That said, you cannot be 100% sure that there is no STD since you had unprotected sex. So you have done the best thing by going for a STD test. Just see to the results.
If you are not getting relived of the itching in 5-6 days, you should consider seeing a Doctor. Diflucan is an anti-fungal. You should not use it for prolonged periods
Meanwhile continue the UTI medication. Drink plenty of water.
Hope this helps.
