Baby slowing down

I am 37 weeks and 3 days and my baby has been rather lazy today. I have felt him, a few times every hour or two but it is much lighter than usual and less than usual. At my last appt I was dialated at 1 and 30% effaced. Has anyone else noticed their baby slowing down this near th end of pregnancy? I have been using a kick counter and of course if I am more concerned I will call my Dr immediately. Thanks.
