Did anyone else experience these at once? My doc prescribed antibiotic and anti yeast tablets 2 in 1 to put in my vag.

I got an std test and normal smear like 2 months ago and it all came back negative while i still had a discharge and now 3 days ago i went to the doctor again and he prescribed these since he was certain I had them because of so much discharge and fishy smell and discomfort with sex like dryness and discharge. Also im planing to start a probiotic once i finish my treatment.

Can the test be nagative and you still have Bv and yeast? Btw I'm going to a private doctor and I paid a lot of money i hope he knows that i really have bv even though it didn't show is that possible??

Sorry for my English girls, it's not my first language, no hate comment please, just some help if you can😭
