Concerning! Baby moving less

Im 23w5d today and literally about a few days ago my baby girl doesn't move as much as she use to. She use to kick me and move around well over 10 times a day. Now its much less. She will stay still (according to me) through out hours in the a.m and id feel a couple kicks around noon and then a few other times after. I don't know why she calmed down but im just a bit concerned. Anyone else?
