I was 29 when pregnant with my first DS. I didn't have the test done because I felt I was in the LOW risk category.
At our 20 week US we found out that our DS had a bilateral cleft lip and possibly palate as well.
This sent me into a spin big time and was sent for further ultrasounds. Whilst having a secondary scan they suggested having an amnio to rule out other possible syndromes associated with a cleft.
I did have the amnio but only because I wanted to know what we were dealing with and if my babies quality of life was at risk. Only then would I make the decision to terminate.

My results came back clear and I carried on with my pregnancy without the concern of anything going to be wrong. He is a beautiful bundle of joy!!!!!!!! I was very scared tho to have the amnio but the statistics of me misscarrying weren't that great so I felt it was worth it!
Having said that even if I had the early screening test you are talking about it would not have picked up the cleft....that is something only the 20 week scan picks up!
I will in future have the test tho and only because I would want to be prepared like we were for the cleft...not because of termination.

I told you my story just to shed some light on the stigma these tests have. It is utimately up to you and what you would do if the worst case senario came back...ask yourself if you would like to know or not????

Oh and by the way his palate was not involved at all so we were prepared for worse case senario and it was the best news when he was born that it wasn't as bad as expected!!!
xoxoxo

Good luck with your decision tho..it is a hard call but your gut feeling will tell you what you should do!
