Kim Kardashian's Doctor -- Divorce Stress Puts Fetus AT RISK!

Kim Kardashian's doctor thinks Kim's unborn baby may be at risk, because of the stress Kris Humphries is causing by dragging out their divorce ... TMZ has learned.

Sources familiar with the situation tell TMZ ... several days ago Kim called her doctor in the middle of the night to come to the house because she was having severe pains. The doctor examined her, but then warned he believed the problems were largely stress-related.

Sources say ... the only significant stress in her life right now is the divorce. And hours before her meeting Tuesday with her lawyer, disso-queen Laura Wasser, Kim's pains returned in full force.

The doctor warned Kim she needs to handle the stress or else there could be "long-term effects." The doctor did not elaborate, but we're told Kim is freaked out her baby may be at risk.

Kim's mom Kris Jenner appeared on "The View" this morning, saying, "Kim has been going through this divorce for months. She has been under a lot of stress because of it and the doctors told her you’ve had a really tough week and the stress could become a problem if she isn't careful."
