Vaginal Odour - PLEASE READ!

So this is a subject I don’t think anyone talks about...

I have had odour for many years since starting contraception, the odour itself is fishy and can be so strong that for years I would wear pads or tampons to try and mask the smell.

I had been back and forth to the doctors who tested for BV, yeast infection and STIs but all clear.

Eventually i spoke with my boyfriend about it and he suggested making some changes and looking at natural remedies. I started washing my underwear in fragrance free detergent, avoiding using soap downstairs and even bathed in apple cider vinegar. It worked soo well till my injection got changed from Depo Provera to Sayana Press. Since having the new kind of injection the smell has come back again, although all the methods I tried I am still doing, the smell won’t go.

My question to you is, does anyone else get a bad smell from contraception or for any other reason? Also, can anyone suggest anything to get rid of it.
