Twin sisters gives birth to their second set of twins

Identical twin sisters Kelli Wall and Kerri Bunker, of Orem, Utah, welcomed their second set of twins just weeks apart. Wall was the first to give birth to twin girls five years ago, and Bunker followed with fraternal twins a year later. Both sets of twins were conceived with the aid of in vitro fertilization treatments. Last year, Wall once again found out she was pregnant after another fertility treatment, and her announcement led Bunker to wonder if she should take a pregnancy test.
"That afternoon I got this harebrained idea that what if I was pregnant," Bunker told KTVX. "We weren’t doing any fertility treatments of any kind."
Bunker not only found out that was she pregnant, but also that she was expecting her second set of twins as well.

"I was somehow magically able to get pregnant on my own, and they are twins, which is crazy," Bunker told ABC News in an interview last fall. "Isn’t it the craziest story?”
Wall said there were some benefits for the sisters to be pregnant together.
"We happened to be sick about the same time, obviously she was a few weeks behind me but we commiserated together," she told KTVX.
Both sets of twins are doing well.
