Baby not moving as much - worried FTM

I'm currently 29 weeks and 4 days. I noticed this week the baby hasn't been moving that much. It used to be consistent morning and evening and I was able to count 10 kicks per hour. Now it's just a few here and there and I don't get the 10 kicks. Maybe 4-5. When should I see my doctor? It's so hard to get an appt.
