Almost 27 weeks. I measured small at my appointment on Monday, so the doctor ordered another ultrasound on Friday. The tech didn't say too much but she thought the baby was right on track. She told us it weighed about 2lb 6oz. On Saturday we cleared out the second bedroom and started its conversion to the nursery. After we moved the bed, desk, and boxes of books, we were reminded how big that room really is - the baby will not lack for space.
