My goal this time is to not gain... hopefully, with the guidance of my OB, I can just maintain .

I didn't gain a single pound while pregnant, and actually walked out of the hospital weighing 30 lbs less than I did before getting pregnant. My doctor wasn't worried, I was just losing unneeded weight from myself while still providing my daughter the nourishment she needed. I walked 5 miles a day and ate very healthy.

31 weeks and I've had a weight gain of 23 pounds. I was normal range before and seem to be gaining in line with the suggested range of 25-35 pounds. Would perhaps like it to be a little less, but the most important thing is a healthy baby! I'm short and bump seems massive. However, hubby is very tall and we know that Baby's femur length is around the 90th percentile, so perhaps that plays a part.

I am 25 weeks pregnant with girl twins and I am suppose to gain 37-54 pounds in the end. So that means my weight could be from 147-164 at the end of the pregnancy.
