I Had my nt scan in 12 week 4 days, my doctor told me to meet genetic doctor, i had my amniocentesis and cvs but yet reports are not came, its been 2 weeks, is my trisomy is very high ? And there are many chances of down syndrome? Please let me know, i read many blogs on internet where there NT measurement was higher than 3.3mm even 6 double than mine, but im confused regarding my trisomy results, and even nasal bone is also present. Why my doctors have scared me badly? They said 50-50 chances of baby to survive. Please help me out.
