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.
Despite being told her new breast would go away following the end of her pregnancy, Billings's OB/GYN was proven wrong when she said the new mother wouldn't lactate in her third breast.
"My milk finally came in for my first born, and while I was nursing him, I asked my husband if he’d turn up the air conditioning because I felt like I was sweating profusely," Billings said.
"It was then that I looked down to see that no, I wasn't sweating, but what I thought had been the tiniest of brown freckles was instead a nipple that was currently dripping milk down into a puddle on my shirt," she continued.
Luckily, her lactation consultant assured the new mother this isn't an uncommon phenomenon. She said she once treated a woman with eight breasts, but the lactation would dry up and the breast would eventually shrink back to normal - as there was no visible nipple.
"Apparently, your milk lines run from your armpit all the way down your abdomen (think a cat or a dog with a litter of puppies)," Billings explained.
"You can be born with extra mammary glands or extra nipples anywhere along your milk line and, unless you have a visible nipple, you may not know it's even there until your breasts swell during pregnancy," she added.
Have you ever heard of a woman having more than two breasts?
