Sharp pain when baby kicks?

FTM...

Recently I was in an accident and was rear ended, baby and I were fine and held at the hospital a couple hours to be sure.

But after a couple days I feel this sharp pain in my very lower abdomen, almost vagina area when my baby kicks sometimes. It’s not constant, doesn’t happen every time, and goes away fast but I just want to know if that’s normal?

I read about a sharp pain that means your cervix is possibly starting to get ready? Maybe that’s it?
