Low PAPP-A

16 weeks pregnant here and found out a couple of weeks ago I have very low PAPP-A. Meanwhile ultrasound last week found a clubfoot. Probably not related and the latter is more or less totally correctable but they suggested an amnio to double check things. Was supposed to have that yesterday but baby was in a bad position for it so postponed a week. I’m dying of impatience and anxiety, wondering if anyone has similar experience/words of comfort. This is second pregnancy after 3 ivf rounds, 5 transfers, 1 miscarriage.
