Normal talaga yan, mama! At 15 weeks, ang baby mo ay mas active na and mas malakas ang movements, parang flutter or light tapping lang talaga ang feeling especially pag early morning dahil you're still quiet, kaya mas napapansin mo. A few of us mums say na parang gas or butterflies lang siya sa simula, pero that's your baby moving around na talaga, so it's actually a good sign!
