If you had skin moles before pregnancy, they may get bigger or darker while you're pregnant. This most likely happens on your face, nipples, armpits, thighs, and vaginal area. You may also notice new moles. Doctors think your changing hormones cause these moles. Usually, new moles that appear during pregnancy are harmless. They often go away after your baby is born.

  • One of your moles changes, bleeds, or increases in size. Your doctor should rule out skin cancer, even though it's unlikely.
  • Regularly examine your skin for changes.
  • Tell your obstetrician if you have a family history of melanomaor atypical moles.
  • Get regular skin exams by a dermatologist during your pregnancy if you are at high risk for melanoma.
