After suffering a miscarriage earlier this year while undergoing IVF treatments, Giuliana and Bill Rancic have had another setback.

Hours after undergoing an egg retrieval procedure as part of her fertility plan, Giuliana, 36, was rushed to the hospital. The trip is documented on the season finale of the Rancics' E! show, Giuliana & Bill.

"I have never seen her in that much pain in my life," Bill said outside of the hospital. "Her worst nightmare is coming true right now."

The next day Giuliana recounted the night's events to her mom and sister on the phone. "Within about a four hour time period, everything just went downhill," she said. "Abdominal pain you can't even imagine in your life. I was screaming at the top of my lungs."

The internal bleeding came as a result of the egg retrieval procedure. "Sometimes there's too much poking and prodding that could cause bleeding," Bill explained.
