I have a yeast infection or so I thought. I have been experiencing the itching, burning and cottage cheese like discharge. I purchased a 1 day treatment kit which I used yesterday. Throughout the day today I've been having really thick, paste like yellow

Infection? STD? It takes a few days for yeast symptoms to clear up. Your initial symptoms were typical, so yeast seems likely. However, these symptoms also could be due to an STD like gonorrhea or chlamydia, but of course only if you have had sex. Best to see a doctor for examination and STD testing. Good luck!
