4 pounds in a month?!

Kortney

I was doing some reading and I saw you're supposed to gain 4 pounds over the course of 3 months. I weighed 113 before I got pregnant and I am 4'8. I didnt eat regularly and I barely drank water or anything other than soda. Now I snack through the day and drink mostly water/juice/milk. I'm 6 weeks and when I went to my WIC appointment around 1 month pregnant i had already shit up to right under 117 pounds. Am i just bloated ?? Why have I gained so much? I'm slightly more active now too so I just dont understand.

My tummy now relaxed no pushing or sucking ^^^
