Check up on heart

I had about a 45 minute ultrasound today at the downtown Memorial hospital here in Colorado Springs. On my last ultrasound they had been concerned about the heart rate range going somewhere from the mid 80's to 160's. Today none of that occurred. They are concerned about her size, she is in the 25%. So on the smaller size. The doctor is recommending that I get checked weekly and ultrasounds every 3 weeks. They want to check Piper's growth and my placenta. He has put the recommendation to my doctor's at Evan's (Fort Carson hospital). He said I will probably be seen there at the downtown hospital since Evan's has to many patients, but I will have to wait and see.  I'm not too concerned about it since everyone on my mother's side has babies under 6 pounds. Any extra sneak peeks we can get of Piper is a blessing.
