lormy: I consulted 龔羽一 when I had my first baby. He is pretty good and quite a number of nurses and doctors seems know him.
Now I pregant 雙胞胎 also. My doctor told me the % of miscarriage of 抽絨毛 is double of 抽胎水. While 抽胎水 is more accurate than 抽絨毛 for 雙胞胎 case.
I have booked 龔羽一 on 12/1.
Wish you good luck.
