A couple whose Facebook photo made viral status earlier this month say the quadruplets they are expecting are all doing fine after a surgery to correct a complication with the pregnancy.

Ashley and Tyson Gardner of Pleasant Grove, Utah, had been trying to conceive for eight years before trying in vitro fertilization this past summer. A photo of their shocked expressions went viral after they discovered in July they were pregnant with four babies, two sets of twin girls.

“The ultrasound looks great – there were four heartbeats so we’re all smiles over here,” said soon-to-be father Tyson Gardner in a YouTube video. “Ashley is doing great,” he added.

Monday, Ashley’s doctors discovered a complication with her pregnancy: One of the sets of twins had twin-to-twin transfusion syndrome, as stated on the Facebook group page dedicated to the pregnancy of the quadruplets. Blood flow from the shared placenta of the twins became unbalanced so that one twin was not receiving enough blood and the other too much.

The couple had to fly to California to see a doctor who specializes in correcting the condition and underwent a successful surgery on Wednesday. The doctor is Raman H. Chmait, director of Los Angeles Fetal Therapy within the CHLA-USC Institute for Maternal-Fetal Health, as stated in the Daily Herald of Utah County.

On Thursday, they posted a picture to the Facebook group announcing all four babies were alive.

Another fatal problem was discovered after Ashley arrived at the Los Angeles hospital – her cervix had opened while on the flight. Dr. Chmait performed a cervical cerclage which sews the cervix shut. However, Ashley’s father Steven Weisenburger declared to the Herald, “If we hadn’t gone down on Tuesday, all our babies would be dead today.”

Just a day after the surgery the Gardners flew home.

Ashley is now 20 weeks through her pregnancy; She will be on bed rest for the remainder of it. The fetuses will need to make it to at least 28 weeks to have a good chance at vitality, but the Gardners “think our little fighters will stay in longer.”
