I had a Biophysical Profile done today for the first time. I am 37 weeks tomorrow and my daughter has a single umbilical artery. The test went really well and I, well I guess the baby, passed with flying colors. Her breathing is really good, which gives me some piece of mind, and her heart rate is normal, fluid is good, etc. All looked fine.
My question is that at my last ultrasound they estimated her weight to be 4 pounds 8 ounces...this was at 34 1/2 weeks. The reason they did that ultrasound is because I was measuring two weeks behind what I was supposed to be. Anyhow, they weren't concerned, just said she was a little small. Well today at the Biophysical Profile, the tech estimated her weight to be 5 pounds 11 ounces, which I thought was pretty good since it's only been about 2 weeks since the last ultrasound. She said though that the baby will still be on the small side when she is born. She said that at this point babies usually gain about 1/2 a pound a week. I am thinking if I make it three more weeks to my due date, that would be another pound and a half, which would put her close to the 7 pound mark....maybe a little under. Why do they consider that to be small? My first daughter weighed 6 pounds 11 ounces when she was born and while she wasn't huge, I didn't feel like she was too small. I am just curious what they base this "normal weight" on?
