Less movement

Since 18 weeks I've felt my girl kicking and squirming around a lot every single day. Now I'm 22 weeks and I haven't felt her move in 3 days. Is this cause for concern or still too early to be worried? I'm starting to freak out thinking something could be wrong with her. I know I could call my doctor, but they would want to see me today and I'm trying to save my PTO for when she gets here. Has anyone else experienced this?
