Confusing Pregnancy update

So this doesn't really make sense, but the ultrasound results say the baby is in the 59% for height and weight, they even chart it out, but the height of my fundus is still like 3 weeks behind. As a result I'm going to be doing non stress tests twice a week. I guess the baby is just really curled up or something. Also, now I can totally feel the pregnancy symptoms full force I'm way tired all the time and I'm getting swollen in my hands and feet, but don't worry no pre-eclampsia. Just a few more days to go!
