Oo normal yan, mommy! Around 5-6 weeks, anywhere from 110-160 bpm is actually okay pa, ang baby's heart is still developing kaya it varies. One of my mum friends had 118 at that stage and the OB said it was perfect, so don't worry yourself. Pero if you want to be extra sure, better ask your doctor sa next checkup what the ideal range is for your baby specifically kasi bawat baby different, okay? Congratulations sa pregnancy mo!
