I lost so much weight being sick in the first tri with #1 that I hadn't gained all of it back by 20 weeks. Ugh. Everything turned out fine (healthy baby, normal weight, gained about 15 lbs eventually) but I would sacrifice the sickness for some extra lbs any day. OP, you sound like you are in store for a healthy pregnancy from a weight gain perspective. Congrats on your soon to be bundle of joy!

In my first pregnancy I had only gained 2 lbs by 20 week. I lost lots of muscle though and I think that resulted in a low net gain. This time I am up 5 lbs already at 10 weeks! I started at only 92 pounds this time so I think my body is just trying to build up some fat stores. I was probably a bit underweight so I'm not surprised I'm gaining faster this time.

I am only fifteen weeks and right now I am down about 6-7 pounds. However I started out overweight so this isn't a problem for me. Assume I will be near my starting weight around week 20.
