I had a friend who didnt test for the same reasons as yourself. YOung and for religious reasons wouldnt terminate the pregnancy regardless.
The test may just worry you for no reason.

I did the test with my 1st baby and got a really low probability of having downs syndrome. I am pregnant again and my DH doesnt think we need to do the test again. I just want to do the 12 week US so I can see the bubs.

Wishing you a happy and healthy pregnancy
