The Athiest Is Praying :)

KC started having really bad pains yesterday.  She wasn't bleeding or anything, but her stomach was cramping.  That's how she explained it.  So she took a left over pregnancy test and it said negative.  Then she went to the doctor and they sent her for an ultrasound.
She would of only been about six or seven weeks.  At the ultrasound they told her it was inconclusive and she is booked for aother one in two weeks.Alot of people think it would be better if she lost it, I'm not really one of them.  That is an emotional battle scar that I don't wish for her.
But what are the chances the baby is still there?  After a negative and an inconclusive US?
