High Risk Pregnancy

Emily
I was wondering if plus size pregnant women are automatically considered high risk? If they are what does entail exactly? Does that mean bed rest? Does that mean no working? Or does it just mean ultrasounds and check ups more often with a high risk doctor? We are currently trying to conceive but I'm worried about being told I can't work anymore once pregnant. A coworker of mine was told that her pregnancy was high risk and she couldn't work until after the baby was born unless she could find a desk job.
