Hi everyone, girls ) At 30 weeks my baby weighed about 1200 grams; by development they estimated 29 weeks. The gynecologist is worried that the fetus is small. I had a Doppler done as recommended — the blood flow is all normal, no abnormalities. The ultrasound is normal too. My belly isn't big either; I've gained 6 kg since the start of the pregnancy. I'm worried that the baby weighs little and that something is wrong with him (( I eat normally — how can I increase weight? Any vitamins??? Has anyone else experienced this?
