Leasha - like you I was in 2 minds about having my NT scan done (could probably search under "Nuchal"). I knew that if there was some "problem" that I wouldnt terminate. However, as you said, my thoughts were along the lines of - if there is something wrong I/we could prepare for it and prepare our families. For me, if there had been something wrong I would have quit work instead of taking maternity leave and financially it would have made things harder. So I guess being prepared is a good thing and having the scan does not mean having to terminate. Since having bub (NT scan was fine, baby is fine!) I have realised how much harder it would have been if she had a disability and we didnt know.
I say go with your gut!
