Encouragement needed

Hello all I was at work today and one of my co-works who's know that I am pregnant came up to me and tapped my back repeatedly saying oh I can see you are slacking at the gym there I see that back fat now. I got married in October and trained really hard to get my body into shape for my dress I went from 173 to 155 then after wedding I have been not watching my diet and gained some pre baby weight already but she really made me so down and uncomfortable with my body:/ I can't shake it out of my head. I'll be two month pregnant tomorrow!
