When a thong just won't suffice, Fourth Phase PostUndi postpartum panties offer style, comfort, and extra support after childbirth. Post-birth you'll experience Lochia, a heavy vaginal discharge that contains blood, mucus, and uterine tissue. It will be a heavier flow than you're used to, and will typically last for four to six weeks. That's where PostUndi comes in.
Each pouch includes two pairs of soft-stretch boy-short panties, designed with light compression technology to hug curves and postpartum pads, helping you feel more comfortable and secure while you heal.
Fourth Phase is a social impact maternal wellness brand with a mission to connect moms globally. A percentage of each purchase allows us to donate similar afterbirth care products to unhoused new mothers in the U.S., and underserved mothers in sub-Saharan Africa, via our charitable partners.
