Uy, normal yan mommy! Around 15 weeks kaya yan ang quickening, parang bubbles or popping sensations in your tummy, lalo na pag first time mo. A few of us moms felt the same thing and nag-panic din kami thinking abnormal, but doc said it's baby moving na, or gas lang talaga combined with how baby's growing. Pero if parang cramping or may bleeding kasama, o if worried ka talaga, better check with your OB na lang para peace of mind mo! Congrats sa pregnancy, mama!
