Hello, at 12 weeks the risk for Down syndrome by biochem was 1:259, the PAP-A was low according to ultrasound until the 3rd screening everything was good. At 32 weeks we found DMPJ of 1.7 mm, at 37 weeks another ultrasound showed two myometrial DMPJs of 0.16 and 0.18 cm. I am worried about one hole, I was worried before, now there are two. Who had this?
