I think you would probably get more responses on the pink board, there is a link at the top of this page, pg after DE. Anyway, you are lucky your symptoms are subsiding but don't be too upset if they come back again. I am told the nuccal test with blood results is 98% accurate, I didn't do any blood tests with my twin pregnancy however as I had awful panic attacks with a previous pregnancy blood results which came back very high risk. Normally symptoms tend to subside a lot by 12 weeks and you feel great in the second trimester, hope you are one of those lucky ones. I puked for 8 months and lost 34 lbs in my twin pregnancy - at least I had nothing to lose after delivery but it wasn't pleasant.
