Squidipa: A low PAPP-A alerts to placental function which when compromised affects the baby's growth. I have seen this frequently with low PAPP-A - however conversely I have seen babies with no growth issues with a maternal low Papp-A.

It is a waiting game and as another poster accurately said - the problems don't generally present themselves until after 20 weeks.

You do need monitoring and you do need it with a specialist. I would highly recommend you get some assessment at a fetal medicine unit. Knowledge is empowerment!
