Huy, totally normal pa yan! I didn't feel mine until around 20 weeks, and a few of my mum friends swears na mas late pa sila before they felt the kicks, especially if first pregnancy mo or if your placenta is in front. Don't worry, once you feel it you'll know exactly what it is, promise! In the meantime kung may concerns ka or gusto mo lang mag-confirm, ask your OB sa next checkup, they can listen sa doppler and assure you na everything's good. You'll get there, mama!
