Oo normal lang yan, lalo na kapag tulog lang si baby or nasa rest period, hindi palaging ganap ang movements kaya don't worry too much! Since okay naman ang heartbeat mo kahapon at active pa rin siya, that's a good sign, pero if you notice talaga na bumaba ang movements or hindi na ganap compared sa usual pattern mo, mas better kung i-follow up mo with your OB lang para sa peace of mind, especially since first time mom ka pa, mas comfortable kaya mas matulog ka ng mahimbing hehe, one of my mum friends nag-alala rin ganito noon tapos okay lang lahat, the movements just vary throughout the day talaga!
