HI Robin,
The nine of swords is sometimes associated with this, but my interpretation is:
The Nine of Swords speaks of emotional troubles of a psychological nature, born of our fears and self doubts. In reality, there may not be any reason for this suffering, except for the person's inner demons. This card warns us to abandon negative thinking, and to believe and have faith in our future, based on our positivity and ability to manifest clear, concrete goals and visions. We need to move beyond the inner dialogue that tells us that we 'can't' and embrace wholeheartedly the notions of hope, fortitude and achievement.
As far as a miscarriage goes, I would say it is pertinent more to the child's soul progress rather than the mother and father. So, a reading should be done for the child.
Happy New Year,
June
