Should I wait until my six week check up to have my doctor treat it ? Or should I call now and see if they will go ahead and prescribe me antibiotics?😔

I know I have it because I’ve suffered from it for almost a year now, especially when I was pregnant. I have had really bad itching the past few days and just went to the restroom and smelled that rank BV smell (TMI) I know it too well😭😭

IDK HOW I KEEP GETTING IT! I wanna cry!🥺 how do I keep it gone after I take medicine?

And will taking antibiotics for it will It effect my milk supply since I am exclusively breastfeeding?): ...... UGH
