Please help!

Melissa • Married to the love of my life! Had my sweet Madison on 07/31/15 and now due with baby #2 Oct' 16.
I haven't really felt my baby girl move as much as I usually do. I've tried laying down and moving her but it's not working, she's usually pretty active when I'm at work. I'm 34 weeks and 4 days. Should I call the dr? I felt her a few times earlier that was it. And it feels like my stomach keeps getting rock hard, no pain or anything like that.
