Alah, ada ja mommy macam ni! One of my mum friends was quite underweight during her pregnancy and she delivered normally without any major issues, doctor monitored her closely especially on nutrition, make sure baby growing well. The key is really making sure you're eating enough and getting proper check-ups, sebab doctor nak pastikan baby okay and you have enough stamina untuk deliver. Aku rasa banyak yang experience macam ni, so jangan worry sangat, fokus je on healthy eating and follow doctor's advice closely, okay?
