Hi I am currently 31 weeks pregnant with twins. All 3 of us were doing great but from my last baby growth ultrasound my doctor found that Baby A is lagging behind Baby B in weight. The percentile difference which should be less than 20% was 21%. I will have another ultrasound next week and my doctor will closely monitor but she told me if baby A doesn't catch up in coming weeks then we might go for delivery at 34 weeks. Anybody here had this situation and how things turned out at the end. I'm a bit nervous, I'm really hoping for 36 weeks.
