29 weeks and less movements? normal?

okay so im 29 weeks and like 3 days i believe ...well since sunday my son hasnt moved that much i still feel him move and such but the movements have changed drastically .....is it normal for the movements to slow down with me not even bein 30 weeks yet? with my daughter she was a light mover so i didnt worry then the day b4 i had her she stopped moving completely ....so does this movement slow down mean hes coming sooner than expected??
