Aw, totally normal, mama! Five months pa lang kaya ang movements ay mabilis pa mag-develop, some babies are just quieter in the womb, and it depends din sa position ng placenta niya kung mahihawakan mo yung kicks. A few of my mum friends said the same thing, tapos biglang naging crazy ang movements ng baby nila sa 6-7 months, kaya just wait lang! But if you're worried talaga or parang less ang movements compared sa last week, better check with your OB para ma-ease ang mind mo, they can do a quick scan at peace of mind is priceless, di ba?
