  • The rash often starts near your belly button and looks like flat or raised red spots

  • Later on, the rash spreads and turns into irregularly shaped, fluid-filled blisters

  • The rash is usually worst soon after delivery and disappears within a few weeks or months

  • Once you've had pemphigoid gestationis, you’re more likely to have it in future pregnancies
