MIL says I'm "too big!" 😭

Taya β€’ Mommy to Elliotte: 7/9/17 πŸ’• Baby due 3/17/19
A little background: I'm a pretty small and fit girl, and my waist was my tiniest area before pregnancy. I also struggled with an eating disorder several years ago (thanks, professional ballet), and there are lots of family members and acquaintances who still think of me as being the tiny little ballerina. πŸ™„ Now I lift and run marathons, so I have more muscle but my belly stayed flat.
Now I'm a few days from 20 weeks. I feel pretty good about my changing body, although there are always those hard days. My doctor is happy with my weight gain and size and I'm just trying to embrace this crazy journey.Β 
But last week at church my MIL said, "Wow, you're really pushing out!" And then later, "you're looking really big for how far you are. No offense." She's made these comments for several weeks now, and it makes me question how I look. My husband brushes it off, but I'm having a hard time letting it go! 😑πŸ˜₯
This is what I was wearing:Β 
And the little bit of abs I have leftπŸ˜‚πŸ˜‚
