Eh sayang, this really needs a proper check with your doctor atau specialist OB-GYN, especially since it changed after Covid. Baby's tummy measurements dapat vary, tapi better safe than sorry lah kan, jangan delay, go for a follow-up scan ASAP to see what's happening. A few of my mum friends ada similar situations and their doctors monitored closely, so your doc will know exactly what to do. Fingers crossed everything is ok! Keep us posted ye.
