I’ve never been this big b4

So my last pregnancies I would start at 110 because I was in a very toxic relationship he was abusive would beat on me cheat on me so at the end of my pregnancies from me already being so little I would weight 157-159 at the end . Im at my 3rd pregnancy now 2 years later & last doctors visit I was 139 im very upset at the start I was 125 .. I used to have an eating disorder where I would starve myself just eat fruit I got to 87 lbs then this was 2016-2017 . My grandmother is always saying smart comments about my body today she said I look so fat 😣😭 my pregnancy hormones are making me so upset Im trying to hold back my tears

I have my next appointment this Monday for my anatomy scan Im 18 weeks n 5 days now I really shouldn’t be this big im thinking of getting a scale so I can keep right with my weight cause this is ridiculous my grandmother kept commenting how she never seen me this big ugh . It’s just triggering me bad .
