For most pregnant mothers, one would easily get bloated up, especially past the four months mark. Estrogen levels will heighten, and the fetus will start to grow, and that is when the stomach begins to show. Not only does the stomach begin to show, but a pregnant mother will start to bloat up here, there, and everywhere, thanks to the heightened level of estrogen. But this is certainly not the case for Sarah Stage. Who is Sarah Stage you ask? Sarah Stage is an American lingerie model, sometimes would dabble into fitness modelling as well. But all heads turn to her when she got pregnant.
