Family fat shaming

Does anyone else have this problem? I'm a former athlete and because of some depression and anxiety issues I've had and a traumatic experience in my life I have gained over  100 lbs since I was in high school, I was 130 and I'm now 240.. My parents are constantly commenting on my weight and how fat I am.. My father is overweight and at risk for another heart attack and won't help himself but constantly comments on my weight and how unhealthy I am.
I'm not blind, I understand the importance of my weight and being healthy, but I still have a lot of the muscle I had when I was younger, my boobs have gotten huge and I do have a bit of a gut now. My husband loves me and encourages me to be healthy but has never said one thing about my weight. 
I am pregnant now and all my parents can talk about is how I am hurting my child, I lost 10 lbs my first trimester because I was unable to eat but that's still not good enough.. Comments like "you shouldn't gain a pound while you are pregnant because of the weight you are at" and "you are putting your child at risk to be disabled because you didn't wait to have a baby until you were back down to at least 150" are killing my spirit... 
What can I do? Am I honestly in the wrong? Am I hurting my child? I'm not intentionally trying to stay this big, I was working with my husband to loose weight before the baby showed up.. Any advice would help. 
Thank you in advance
