When it comes to building a little baby inside of you, anything that gives you additional support and comfort is always a win, and that’s not to mention that is exactly what your bras should be providing – pregnant or not. As soon as your current bras start feeling uncomfortable, switch over to a maternity bra. After all, your bra size isn’t going to get any smaller until after you give birth so those bras are going to continue to be an irritating nuisance.
