Growing belly and winter

How is everyone else managing who actively wears jeans and other pants (meaning not dresses, skirts)? Where I live it tends to get pretty cold in the winter for which I wear warm outdoor gear, when I’m hiking etc I have my hiking pants, at work I like to wear pants instead of leggings especially during fall/winter because, well, it’s cold on the way to the office and I can not survive without layers 😂. Am I doomed to purchase maternity clothes or just wear my three pairs of sweats 🥲?
