There must be something in the air at Maine Medical Center.

Nine nurses -- all who work in labor and delivery -- are pregnant. And they're all due between April and July this year.

"After each one of us started to say, 'We're pregnant,' I think it was a happier announcement each time, and we're all there for each other," nurse Erin Grenier told ABC News affiliate WMTW.

Eight of the nine pregnant nurses -- Erin Grenier, Rachel Stellmach,Brittney Vervill, Lonnie Souci, Amanda Spear, Samantha Giglio, Nicole Barnes and Holly Selby -- were photographed at the Maine Medical Center, which then posted the photo to their Facebook page.

The photo quickly garnered lots of excited responses for the group.

"It's really nice coming to work and seeing other people who are just as pregnant and watching their bellies pop and just talking about these experiences that we are going through together," nurse Amanda Spear said.
