Well, this came as a surprise, since we tend to have hefty babies in my family. But the ultrasound Friday showed that the baby is smaller than average(estimated to be about 5 lbs, 2 oz . . . in the 18th percentile). Everything was normal (movement, fluid levels, bloodflow, placenta) but the baby is just a little peanut.
We have to go for follow up ultrasounds for the next two Fridays, and this Friday will include a nonstress test (when they watch the baby's movement and heartrate for a while) and some other test that I've forgotten already.
Also, I'm going to have to cut back on work, for two reasons. The more active I am, the more calories I'm using and at this point I need to keep all of them to fatten up the baby. Also, if I'm on my feet less than it's less likely that I'll go into labor early, and we want the baby to stay on the inside for a bit longer.
So this is a little stressful bump in the road. I'm trying not to worry too much, and to eat a lot of ice cream :)
