Weight gain

Kristin
Im 36+1 and feel like I'm gaining to much weight at the end. Last week I gained 2lbs in one week. So far this week I already gained a 1lb. 
I've been on track gaining a 1lb a week through out my entire pregnancy. I was pretty sick from the start and weighed 102 now I'm 137.2. 
Anyone else gaining a lot at the end?
