But just as many followers posted negative comments.
“Where's this baby hiding at?? Definitely not her tummy!!\" one wrote, while many others suggested she was somehow harming a baby and should seek medical attention.
Stage told \"Good Morning America\" a lot goes through her mind when she reads those criticisms.
“I don’t know how someone could say something like that to a pregnant woman,\" she said. \"I think that is so rude. My baby is healthy and we are happy.”

Stage said she has gained about 20 pounds so far. And that’s exactly where she needs to be at this stage in her pregnancy, according to Dr. Jennifer Ashton, ABC News medical contributor and a practicing Ob/Gyn.
“The fact that she looks skinny on Instagram does not mean her baby growth is restricted or too small,” Ashton said. “It has nothing to do if you can see her muscles if her uterus is the perfect size and she has gained an amount of weight that is acceptable.”
Women should gain between 20 and 40 pounds throughout their pregnancy, according to the American College of Obstetricians and Gynecologists. Because she is young, tall and slim, and it is her first baby, her small bump size is not all that unusual, Ashton said. And her tummy will no doubt grow larger in the coming weeks since most women gain about half a pound a week in the last month of pregnancy.
Ashton is also supportive of Stage’s twice-weekly workouts.

“Pregnancy is an incredible physical feat and labor and delivery are athletic events so training for them isn’t such a bad idea,” Ashton said. “Having stamina, strength and muscle tone are good for both mom and baby.”
Besides, pregnancy is not a disease, Ashton said, and if Stage is following doctor’s orders, she should be fine.
