Body Image Issue

Any moms or mom-to-be who has body image issue? As a kid, I was made fun of for my weight so I don’t want to gain weight at all for my pregnancy (currently 15 weeks). I also dislike the look of being heavily pregnant so I’ve been tempted to get a corset to ensure I don’t start showing. Any one went through this and have any solution or advice? I don’t want the child to be unhealthy afterall 😕 #1stpregnacy #advice #advicepls
