Rude comments at work about bump

I work in the medical field with nurses and people who know what the pregnant body looks like yes I’m receive horrible comments from my coworkers. I’ve been asked if I was fat or pregnant, asked if I have always been this fat, asked if I was having twins, have been asked about what I’m eating many times implying I am just gaining weight and have had various other comments about my weight. I have a very petite body, I’m very short and my torso is super short so my bump has stuck out since like 18 weeks. I feel like I look normal but everyone is making me feel like fucking shit. This is my first pregnancy after 4 losses so it really really hurts me that I feel embarrassed to wear tight shirts or embrace my bump. Idk what to do or say to them to stop it because I just run off to cry in the bathroom when it happens.
