Don't believe in the stats and any negative reports from ANYONE, but BELIEVE in GOD. Find your sister some healing scriptures and read them daily....you can also. Believe in the Word of God for a long quality life and don't allow anything to change your thinking. I will pray for your sister and unborn child....I'm only giving you the advice of what I've been doing...my BABY is 11yrs old and that's just what we've been doing to get us through.
Be Blessed
