Aiyooo, normal je lah! Especially kalau pregnant, weight gain mmg akan fluctuate, sometimes 2-3kg in a month is totally fine, depending on your stage of pregnancy and water retention lah. A few of my mum friends also experienced the same, especially during the second trimester when appetite was gila gila But since your nurse keeps mentioning it, mungkin baik check with your doctor just to make sure everything's on track, they'll look at your overall health, bukan just the scale number. Main thing is you're eating well and baby's growing properly, so jangan stress too much okay mama!
