First baby Stomach Pains

Cl
It's my very first baby. I've never been pregnant before. This is the first time I've felt stomach pains like this. It's about the middle-ish/right side of my stomach that hurts. It's a distinct feeling as in, I can tell exactly where this pain is. It's a little sharp. Hurts if I move too quickly or twist around to grab something. Should I be worried? I've not been to a doctor yet. I found out 4 days ago I'm pregnant. Please help.
