Today I'm 8 weeks 3 days pregnant due April 18th 2010?

Yay! Congrats to you. I am exactly 8 weeks 3 days, due on 4/18, as well! This is my second, though, and another high-risk pregnancy. I feel cramping and pulling/stretching all the time. It's your uterus and muscles making room for baby. I also lost weight in the first trimester in both pregnancies, and it was never a concern. As long as your doctor is monitoring you and your weight, they'll let you know when to worry. So...yes, all you are experiencing is normal! Good luck and try to stay stress-free!
