Does she by any chance have a history of miscarriages? That's the only way I can see her statement being even remotely understandable.
I would get comments like that too, although not quite so insensitive. Like PP said, they were made to make me feel better and help me "look on the bright side." The way your friend phrased it, though, almost sounds like she's essentially telling you it's not that big a deal, which is incredibly insensitive.
This doesn't sound like a "go to with your troubles" friend.
