If your Chinese Dr said still got chance, you better lie on bed as much as possible and keep asking BB to 'add oil'!!! don't give up yet.....may be BB is just abit weak now......talk to BB more!
Of course in the worst case if BB really can't develop well, we still should be glad that B leaves peacefully and no need to suffer....last year I carried twins and everything seemed normal....just suddenly stopped heartbeat on their 4th month too.....but at least BB didn't give me any pain or discomfort and they must know and feel the love from mother....
So, don't give up so soon......just let GOD to decide for you...keep praying!
