I am 18. I don't know whether its normal, I'm pretty sure it's not. I know vaginal discharge is acidic, but this doesn't really make any sense to what's happening to me. After washing my underwear, I have noticed that where vaginal discharge has touched my underwear, there are discolourations to my underwear. It looks as if it has bleached my underwear as my knickers are different colours, and where it has touched the discharge it has turned the knickers yellow/white. And the colour of the knickers has literally been taken out. The colour of the underwear is not fading anywhere else, it is just where discharge touches. Therefore I am spending a fortune buying new underwear frequently as it is slightly embarrassing to where them with discolourations to my boyfriend's house!
Surely if the discharge is "bleaching" the underwear, it would be alkaline, rather than acidic?! Or am I just confused.
