I stopped my last depo birth control shot a few months ago in June. Lately these past months I've noticed my vagina has been itchy but it's only every once in a awhile after I end my period. Everything I look up about stds doesn't exactly match my symptoms. I have been also using condoms a lot with my husband because Im not longer on birth control. I'm honestly scared to ask my doctor what's wrong.So I thought id get some info before I ask. Now the itching and burning "burning from itching alot" only happens sometimes andand thenthen It goes away and then comes back after a few weeks or even a few days. I have also taken a lot of antibiotics in the past because of heart surgery and frequent yeast infections. The thing that scared me the most was when I found pink white flesh particals in my underware that smelled horrible. I need help or some sort of advice. This is getting irritating.

' I have also taken a lot of antibiotics in the past because of heart surgery and frequent yeast infections.'
Antibiotics are not used to treat yeast infections, only bacterial infections.
For me and for many women, antibiotics bring on yeast infections (although they stopped for me when I hit menopause).
I'd see your doctor, even though you can go buy some Monistat at a drugstore.
