9 labor and delivery nurses at Maine Medical Center pregnant at the same time

The stork will make nine visits to Maine Medical Center between April and July.

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.

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.
