Sudden hunger and weight gain!

Abby • 33 years old. Married to Eric. Mom to 2 boys that are 3 years old and one year old!

So up until this point I have been right on track with weight gain according to the week I’m at. This last week was a sudden increase in 3 pounds!!! I didn’t eat good last week due to my work baby shower, company over, and my sons 2nd birthday. Last week I was measuring 35 weeks last week right on track. I will be 36 weeks Thursday. Do people gain weight more in the end??? Also they increased my iron so I barely can go to the bathroom ever so I don’t think that’s helping!
