hello i suffer from this and gotten worse since my menopause and no periods..non specific vaginitis can cause fishy smell as for unknown reasons the bacteria multiplies through stress or change of partner..some spermicidal creams also used with barrier contraceptives may also cause it and unfortunately no specific cure yet...loads of us women suffer it and have been various threads on the forum regards it so your not alone..
I use cranberry juice and find it does help but not take away fully..
my doctor explained it too me as i was embarrased by the odour..so no need to worry its not anything you have done and its hormonal..

Angeln! You are not alone i cannot figure it out to save my life i have been to the DR multiple times with the same symptoms! And i to have noticed it only happens after intercource and before and after my cycle! I have tried antibiotics and creams nothing has helped! It is a very embarassing problem to! I am tempted to have it removed! I also would like to know what to do about this problem!
