Feeling Baby Move??

I'm 20.5 weeks and don't think I've felt my baby girl yet. It's my first pregnancy so I know it could take a little longer, but I'm getting anxious! I know she is healthy(we just had our anatomy scan) but I want to feel her!!! A few days ago I felt a Pop feeling that startled me while lying on my side, unsure if that was movement or just growing pains? Anyone else still waiting?
