35 weeks pregnant: Not uncommon at 35 weeks. Hopefully you see your obstetrician regularly to discuss this. If not please make an appointment or at least call the office. Ps: my twin granddaughters, now age 7, were delivered very early and very small, and are doing just fine - great girls and your baby will have good care at delivery and beyond.
