Is there a such thing as a sleep schedule this early for babies in the womb?

my doctor told me that even though babies don't get time, there is a point in days where they are always resting or napping

I think so. My baby moves from when I wake in the morning. He moves and kicks a lot until around 8-9pm. Then things quiet down and I'll feel him very sparingly.

my son usually sleeps when I do now
