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.

Call Doctor If:

  • One of your moles changes, bleeds, or increases in size. Your doctor should rule out skin cancer, even though it's unlikely.
