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!
This is so unusual! Bridee and I both had single umbilical artery's with our babies, and guess what we called them? Holly!! With my pregnancy, there was never any restriction in the blood flow from the placenta through the cord, so we assumed the artery was just larger to make up for the other one.
Holly - It is a little early to use notching as an alarm bell as it is sometimes just artifact at this early stage.
A single artery happens sometimes with no other problems - sometimes it is due to other issues with the baby (sometimes cardiac). All of this though is an unknown quantity right now.
Right now your litle one is growing and in another month or so a more detailed u/s will give a more accurate picture.
Wishing you lots of support along your journey - remember we are here to support you.
Holly - as you may have read in previous posts we did have restricted blood flow through the cord at times and then the next week it had corrected itself, this happened around the 28wk mark I think. It was a case of just regular monitoring. My ob said that with these issues (low papp-a and single umbilical artery) problems don't happen quickly so if something was picked up in an ultrasound it would be rechecked in 1-2 wks to see if it had got worse. In my case the repeat scans when issues had been detected, showed the problem had eased.
Just to let you know as well my DD is doing fabulous (could sleep better during the day but that is any baby). She put on a lot of weight early on - going from barely on the growth charts to know being in the 25th%, so in my experience they do catch up in there own time.
