Xa wenza i-ultrasound, oogqirha baqaphele ukuba i-chorion kunye nomgca wayo osezantsi uvalela nje ukungena kwesibeleko.
Yiyiphi ingozi engumngcipheko we-chorion?
Xa ufumanisa le ngxaki, oogqirha bathabatha umfazi okhulelweyo ophantsi kolawulo. Into enje kukuba eli lungiselelo le-chorion landisa umngcipheko wokuphuma kwamanzi, okwakungakhokelela ekuphazamiseni ngokupheleleyo ixesha lokunyuka.
