Such as the NT scan, or blood work tests for Downs and Spina Bifida? I have heard of there being a lot of false positives, (my sister had a false positive) and I just wouldn't want to worry for no reason. We were so worried about my sisters, they thought that her little girl could have spina bifida, and she was fine! Our percentages for downs was low based off our age and family history, and I would never terminate my pregnancy if I did find out something. And my doc said that they would usually catch something by the time I would be 20 weeks along anyway based off the ultrasound. So, I don't think I'm going to have all of them done. Does anyone else feel this way too?
