Pre seed cured BV??


A little background for myself. I have been having infection in my vagina area more commonly known as BV. Usually when i pee it will lead to a strong fishy smell. Sorry if this gross you guys out there, but it's really irritating to keep having it all over again (i have consumed meds prescribed by a doctor but it was last only for a short while until i'm getting the fishy smell again). & so recently i purchase pre seed for TTC purpose. Somehow after using it for several times, i didn't have the smell anymore which is kind of weird. Is anyone ever experience the same? I really don't know if pre seed helps to cure the BV.??
