16 week prenatal appointment

I had my 16 week check up today. I have gained 10 pounds so far, my blood pressure was great and the doctor said that so far my blood sugars look really good. I hope I won't get gestational diabetes like I did with Nathan. I have been trying to eat low carb foods. The baby's heart rate was 157 and I am measuring right where I should be. My Ultrasound is scheduled for April 27th, can't wait to see the baby again and hopefully find out the gender.
