Pregnant Kim K rushed to the doctors for exercising too much

Is too much exercise bad for pregnant women? I ask because pregnant Kim Kardashian was rushed to the hospital on Tuesday night after she felt ill. She thought she was having a miscarriage.

She was discharged a few hours later with her doctor supposedly telling her to slow down with the amount of exercise she's doing.

Kim is believed to be working out seven days a week and working with two different trainers in a bid to keep the pregnancy weight gain under control.
