Sorry to hear you have to think about all this but 1:2 does mean what you think it does.

Speak to a genetic counsellor (OB should arrange this if not you can contact a major hopsital who will offer them)

Have a think about whether you would want to continue the pregnnacy or terminate and rememeber there are lots of people at BB who you can speak to for support and information.

So sorry for you to have to go throught this, but hopefully you feel that it is better to know before hand and have chance to come to terms with what ever happens, which remmeber there is also a chance that baby will be normal with no abnormallity.

HUGE HUGS
thinking of you
