Normal lang yan, mama! At 16 weeks, marami pang hindi nakakaramdam ng movements yet, lalo na kung first time mo or if you have an anterior placenta na naghahadlang sa kicks. A few of us mums didn't feel consistent movements until around 18-20 weeks, so don't worry. Pero if you're still anxious or may iba pang concerns, okay lang mag-check sa OB mo para sa peace of mind, they can do an ultrasound to make sure baby's doing great!
