Prepregnancy weight around 113?

I'm almost 31 weeks. Weighed 113 at beginning and I'm already at 131.6. I just wasnt expecting to see that number this soon ..I still have 2 more months!! I think what really got me was that two weeks ago, I was 126.4 and then today I get 131.6 😳

My friend that is about the same frame as me only gained 20/25 lbs total. I'm already at 18!?!

Doctor said my weight gain was good. But I'm thinking if I keep going at this rate, it's gonna get bad

Side note...if course I've been eating more in quarantine because I'm bored
