Is this bad for my vagina?

When I'm on my period, in the shower I will sometimes turn the shower head on to the jet setting (it's not a harsh jet) and spray out my vagina (just water, no soap).

I do this once, maybe twice each time I'm on my period, when I really want to clear it out a bit and it helps me feel cleaner.

Well, I was in the shower today and I did it, but then I started wondering if it could be bad for my vagina and maybe I shouldn't be doing it.

Could it be harmful?
