Over washed...

I bought recently soap with ph balanced, "made" for intimate skin, cleaning vulva...

Honestly, since I've started to use it, it itches, and now I have weird discharges and feel uncomfortable down there...

First I thought it was because of sex (condoms, or he was maybe too rough...)

But i'm starting to think it's because I wash my vulva and then it goes a bit in my vagina...

Do you know anything about over washing lower parts?? Have you had this problem before??
