I'm 6 1/2 months pregnant and needed to buy new scrub pants but didn't want to spend a whole lot of money. There are perfect. Because they have a low waist and a fold-down band, they make perfect maternity scrubs. They're nice and light weight also, so they're not too hot when you're running around the hospital. They are true to size, so if you were a medium before pregnancy and haven't gotten too much bigger in other areas, you should be fine with a medium in these (I'm talking scrub sizes though, which generally run a bit large to begin with).
