Vaginal cramps

Ch

When I am on my period, I get these almost "shock" or "sharp pains" in my vagina that last a few seconds and then go away.

They're not like period cramps in my pelvic area. They actually feel like they're in my vagina?

At first I thought they were from my tampons.

But I decided to stop using them 4 months ago, and I still get this feeling.

Is this normal on a period?
