After her first pregnancy, a woman had discovered a kiwi-sized breast growing in her armpit.
In a freelance post to ScaryMommy, Billings said she asked her OB/GYN about the unusual growth, but she proved to be little help.
"I was told it was just breast tissue, breasts swell during pregnancy, and that it should go back to normal after giving birth. This was a great theory but, after looking around, no other pregnant women seemed to be walking around with a kiwi in one pit!" Billings wrote.
While relieved her armpit would return to normal, Billings was told by a lactation consultant that the third breast could actually be an extra mammary gland, which was proven to be true after the birth of her son.
