Odd pain?

It's been a while since I've been pregnant so I can't remember if I had this or not with my first.

I've been having mild/minor sharp pains here and there that last a couple seconds then go away.. on and off through the day, the last couple days. Sometimes I'll get a shooting pain straight down my vagina (it feels like anyway). Don't feel like cramping or round ligament. 15 weeks 3 days. Just curious if any ones having/had anything similar. Don't want to have to call my doctor unless it's necessary as its a 2 hour drive for me.
