Hello ask lang po if normal lang po ba body weight baby ko 181.07 gms.(6oz)

Mamsh, that's something best discussed with your OB sa next ultrasound kasi sila lang ang makakasiguro based sa full picture, baby weight estimates can vary depending on the machine and technique, at that's totally normal. Ang importante lang ngayon is you're 18 weeks in, so enjoy this stage at ensure regular checkups, okay?
