I'm 24w and my last scan showed baby had dropped from 30th centile to <5th centile in 2 weeks. They said not necessarily alarming as I am quite petite but they have referred me for another scan next week. I'm concerned that I haven't been gaining enough weight. I don't feel underweight and I've gained 4kgs from my pre-pregnancy weight. I've been tracking it on my Ovia app and I'm only about 2kg below their "ideal weight" at this stage (based on pre-pregnancy weight) Should I be eating more? Or higher calorie foods? Is it a direct correlation on my baby's drop in weigh centile? Gosh pregnancy worry never ends!
