Are pregnant women allowed disability benefits in conditions where there pregnancy prevented them from working for weeks?

Social Security Disability Insurance does cover medical conditions that prevent a person from working.  The rules are very stringent.  Your medical condition must significantly limit your ability to do basic work activities—such as walking, sitting, and remembering—for at least one year or result in death.  Another requirement under Social Security law is that the severity of your medical condition or combination of conditions meets or equals that of a listed impairment.  The Listing of Impairments are those medical conditions or illnesses that are considered to be so severe that if your condition is the same or equivalent to it, you are considered disabled as a matter of law.  Social Security does not pay temporary benefits.  Your pregnancy will not last 12 months, so it would not qualify as a disabling condition under Social Security rules.
