not so active baby - ftm - 19 weeks and 4days

Hi mommies! around 17 weeks I can feel my baby's flutters/small movements but mula nung 18weeks na sya at now na 19weeks and 4days na ako, I do not feel my baby so much like when I'm at my 17th. Nagdadoppler nalang ako once a day lately to check on his/her heartbeat, stable naman so far. Naiinggit lang ako sa ibang mommies na active na babies nila at this point. Any advices po? Normal po kaya? thank you in advance and God bless. #TeamJune2020
