Girls hi! On the first screening they said there's suspicion of Down syndrome! The Pap test came out at 0.40. Normal is 0.50. Now it's 16 weeks and I refused the puncture, waiting for 2 screenings, tell me in the second screening will definitely say there's a disease or not? And is there anyone with low Pap-A who gave birth to healthy children?
