What to do if i'm having feelings of passing out during pregnancy?

Call 911: Unfortunately, immediate evaluation is needed. The condition is, most likely, not as dangerous to you, but it could very well be for baby. Trauma could occur with fall, or inadequate blood flow to baby, could both result in loss. Don't take chances, call 911 or see PCP immediately to get an evaluation started, then treat your condition appropriately to reduce risks to you & baby.
