+ Size Moms-to-Be

So before pregnancy I was 266lbs...Which is considered + size in my case but considering my height (5'6") everything was kind of weighing itself out. I've only gained 4 lbs luckily but lord, the way my boobs have been growing!!!! They're so heavy I feel like I'm gonna need a breast reduction immediately after birth lol. My question tho is when have you ladies started to show? I'm 21+3 and to others I'm already "showing" but I can't tell myself 😩
