Shooting pains? 8-9 weeks

So I will be going in to see my OBGYN tomorrow for an ultrasound but I wanted to ask here for a peace of mind. I'm about 8-9 weeks and today when I got done with my shower I felt this shooting pain through my stomach/uterus. It wasn't anything very painful but it was noticeable. It was an on and off pain that went on for about a minute or two, and now it's stopped. I'm just curious has anyone else felt this before? It reminded me of the same feeling you get with that shooting pain in your crotch, it felt like that. Is it just things stretching out and adjusting or should I be worried about my baby? I haven't had any bleeding at all.
