Hello mums, I'm 16 weeks tomorrow. Three weeks ago we were told there's a 1:15 chance of downs syndrome. We decided to go for the CVS,but they couldn't do the procedure because the placenta was in the wrong place. A week later we went for the amneocentisis. Today another week later we were expecting the realists but instead told my sample was contaminated with blood and will have to wait another two weeks for results,with a risk they may not get one. I'm so scared I'm moving along in my pregnancy without a sure answer. I have a high risk because I'm 37 with a low PAAP-A reading. Not is fine and baby growth all good,but I'm beside myself waiting.has anyone experienced this. Is there a chance they not get a reading. Should I now go for a harmony test just in case?the. results would be due the same date for thaton't know what to do. Any adv
