Hello! I happened to be 6 weeks pregnant and according to my transvaginal ultrasound, my baby has a small sac. My Ob gave me Duphaston, 30pcs, to be taken 2X a day. Is ot safe for the baby? I heard that Duphaston was banned in the US because accoding to waht I read in the net, it causes fetal abnormalities. Is it true? I am deeply worried but I have no choice but to take it because it was prescribed by my OB. Many many many thanks!
