Mine has come back again. The antibiotics seemed to help. Although the swab my doctor took came back as normal, there were NO infections (she didn't want to prescribe me the antibiotics because she couldn't find anything wrong, but I insisted on having them).
Anyway, my 'smell' has come back within the last week. The only thing I can associate it with is stress. I have been very stressed lately and if I think back, when it went away I was generally feeling better in myself... and when I had the smell the lastime I was feelng very down and stressed. So basically, I am wondering if mine comes on in times of depression and stress (I suffer with depression)
BV normally causes a fishy odour, not a 'rotten' smell. I actually suggested this to my doctor and she frowned and said no. BV also normally comes with itching too... I do not have any fish odour nor do I have itching. So to anyone who is noticing a fishy odour along with the rotten smell and some itching, I believe you are could have BV... and you can buy treatment over the counter.
I don't know what mine is, like I said the doctor said I was clear of infection. I think it's just something I'll have to put up with at certain times.
