Way too much weight gain already

Before the start of my most recent period, I weighed 106 at 5’4. I’m 5 weeks today, and I’m at 122!! My appetite has been realllly big and my stomach has been extremely bloated since week 3. I look giant already. Any advice? I struggle with body image and I really only wanted to gain the recommenced 25 to 35 pounds but at this rate it looks like I’ll be gaining a lot more. Bleh.
