Pain when baby moves

Sara • Rainbow baby 🌈 due December 2016!
Has anyone experienced any pain when baby moves? I'll be 23 weeks tomorrow, and my little boy has been very active lately (which is reassuring!) However, last night I noticed quick, sharp pains to the left of my belly button every time he moved around in that area. It's kind of sore there today as well. Is this normal? Should I call my doctor?
