Please know and understand that every pregnancy is different even though you have been pregnant before. Does not mean you have felt your baby moved from your previous pregnancies, you will also feel it again this time. I believed you have already done your scan & doppler test and have heard baby's heartbeat? If yes, worry not! Everything is normal. Otherwise seek your gynae's advice!
I only felt mine at 19 +2, I’ve got colleagues who only felt theirs after 20+, don worry💙 But if you don feel comfortable suggest you consult yr gynae for a peace of mind😊
try to consult your ob sis.
