Two twin sisters have quite a few bundles of joy to chase around after they both recently gave birth to a set of twins -- again! 
 
 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. 
 
 Wall gave birth to her twins about four weeks before her sister. Because they were born premature, Wall was already at the hospital when her sister arrived for her delivery. 
 
 "I said we're already here so we'll walk down the hall," Wall said. 
 
 Both sets of twins are doing well. 

 (KUTV) Kerri Bunker and Kelli Wall, 36, are best friends and identical twins who do everything together. 
 
 
 
 "We teach at the same school. Our husbands are best friends," said Kelli Wall. "[Kerri] and her husband actually met at our wedding." 
 
 The two families also live down the street from one another. 
 
 "We will have talked to each other 50 times that day, probably, but we still call and tell each other goodnight," said Kerri Bunker. 
 
 The women even had their two sets of twins close together. 
 
 
 
 
 
 "We have nine kids under 5-years-old!" said Kelli Wall. 
 
 Wall gave birth to her first set of twins through in vitro fertilization in October 2010. Kerri and Robert Bunker also used IVF. Eleven months later, Kerri gave birth to her first set of twins. 
 
 After the birth of twins, the Bunkers continued fertility treatments so Kerri could freeze her eggs for future IVF treatments, but they never needed those frozen eggs. The Bunkers were able to conceive their third child, Sadie, through natural means. 
 
 "And we were told we could never get pregnant on our own. Which was kind of a crazy story!" 
 
 The Walls continued with IVF and found out they were pregnant last June. Six days later, doctors told the Walls they were pregnant with their second set of twins. 
 
 
 
 
 
 The day Wall told Bunker she was pregnant with twins, a random thought popped into her head. 
 
 "I got this hair-brained idea that, what if I was pregnant?" said Bunker. 
 
 That day, she found an old pregnancy test and took it.

 "I don't even know what made me think I could be. There was nothing, I mean nothing. And it was just why not? And I found out I was pregnant the day she found out she was having twins. 
 
 Doctors said the odds of Kerri getting pregnant were so low, she was practically barren. 
 
 "I still can't even believe it! My mom and dad said, you know what, obviously these babies need to be here. There's a reason. So we're chalking it up as a miracle and it's all part of our little plan!" 
 
 A few days later, doctors told the Bunkers they were pregnant with twins. 
 
 
 
 
 
 "And we are stunned. I cried happiness tears, sadness tears, scared tears. I mean, we went through the whole gamut of emotions!" said Bunker. "First, we didn't think we could get pregnant. Then we're having two, then we're overwhelmed thinking, oh my goodness, we're going to have five kids four and under. Can we handle this?" 
 
 The youngest Bunker twins were born at Timpanogos Regional Hospital on Feb. 13, 2016. The youngest Wall twins were born about three weeks earlier at the same hospital. 
 
 "When I had my babies she was there helping me and now I don't think I can help her back because we have our hands full with our own sets!" said Bunker. "When you feed them, you put them back in the same spot so you don't get them mixed up!" 
 
 The Bunkers are currently building a new home next door to the Walls. They say all nine kids will grow up together. 
 
 "Two seniors, a junior, and two freshmen! I said, we are not going to be able to afford them! Not to mention, three boys. They're going to eat us out of house and home!" joked Bunker. 

 SALT LAKE CITY (AP) — Identical twin sisters from Utah each recently gave birth to identical twins — again. 
 
 Kerri Bunker and Kelli Wall delivered twins within weeks of each other at a hospital in Orem, south of Salt Lake City. Years ago, they gave birth to their first sets of twins, now 4- and 5-year-olds, at the same hospital a few months apart. 
 
 Bunker's newest twins arrived Feb. 13. Wall's youngest twins were born about three weeks earlier. 
 
 Ryan White, spokesman for Timpanogos Regional Hospital, says some of the twins were conceived through in vitro fertilization. 
 
 The 36-year-old women say they aren't just sisters but best friends, neighbors and co-workers. They say all nine kids will grow up together. 
 
 Bunker also has a 2-year-old child.
– Identical twin sisters from Utah each recently gave birth to twins—again. Kerri Bunker and Kelli Wall delivered twins within weeks of each other at a hospital in Orem, south of Salt Lake City, the AP reports. Years ago, they gave birth to their first sets of twins, now 4- and 5-year-olds, at the same hospital a few months apart. Bunker's newest twins arrived Feb. 13; Wall's were born about three weeks earlier. A spokesman for Timpanogos Regional Hospital says some of the twins were conceived through in vitro fertilization. When Wall found out she was pregnant last year after a fertility treatment, Bunker decided to take a pregnancy test as well, per ABC News affiliate KTVX. "That afternoon I got this harebrained idea that what if I was pregnant," she says. "We weren't doing any fertility treatments of any kind." Doctors had thought Bunker's chances of getting pregnant on her own were practically nil, KUTV notes. Even though Wall gave birth about a month before her twin, her babies were premature, so she was already at the hospital when Bunker arrived to deliver. "I said we're already here, so we'll walk down the hall," she tells KTVX. The 36-year-old women say they aren't just sisters, but also best friends and co-workers at the same school—and now the Bunkers are building a house next door to the Walls. Bunker also has a 2-year-old child, and the sisters say their nine kids will grow up together. "Two seniors, a junior, and two freshmen!" Bunker says to KUTV, extrapolating into the future for her own kids. "I said, we are not going to be able to afford them! Not to mention three boys. They're going to eat us out of house and home!" (Here's why there are more twins these days.)
