Issues... Scared!

I went in for my appointment today. Thankfully, all my blood work came back negative so we are good in those areas. However she had some complaints about me.
1) Since the beginning of my pregnancy, I have only gained 6 lbs. So now, she wants me to gain 2 whole pounds per month for the rest of my pregnancy. I feel like that's too much!
2) On the ultrasounds, we discovered that one of the tubes coming down from Kairi's kidney to her bladder is too short. That being said, we have to go see a high risk doctor every month just like prenatal visits, until she is born. Then, she said they're going to take her from me and run more tests on her once she's out. 
It worries the crap out of me! Has anyone else run into this??
