Ashley and Tyson Gardner of Pleasant Grove, Utah, tried to conceive for eight years when they turned to in vitro fertilization this summer.

Boy, did it work. Or rather, girl, did it work. In July, they got the “surprise of our lives” when they went in for an ultrasound and found out they are expecting two sets of identical twins -- all girls.

A photo of the couple looking shocked while holding the ultrasound images has gone viral on their Facebook page, which also features photos of the moment they first found out Ashley was pregnant.

"My whole goal in opening up about this is to promote infertility awareness," she said in a recent YouTube video. "It's not something that's talked about a lot and it's a really hard trial that people go through."

Ashley's fertility problems were caused by endometriosis, so the couple at first tried intrauterine insemination, she told BabyCenter.com. When that didn't work, they tried IVF, which cost them $12,000 out of their own pockets.

Ashley is now 18 weeks along and she and her husband are busy trying to pick names for their four girls.

"We were so blessed," she writes on her Facebook page.
