First time mama.

So I'm 17 weeks and 4 days. Having a little girl I feel her flutter somewhat frequently and its not hard its like a medium and i don't feel her everyday. We went for an ultrasound 2 weeks ago and she moved SO much like constantly moving.

I have friend who are 18,19 and 20 weeks and up and they feel their baby's kick and move and some are at the point their S/O can feel them. My husband is so excited to feel our little girl kick.

My question is, is it normal not to feel her move all the time and should I be feeling kicks at this point?
