@Ashchinna Hey hun!
Ok so... where to start. First thing is I can only talk about my experience personally so if you are truly worried even after reading this then please speak to your midwifery team.
I have a healthy happy 2 year old! So that's always a positive way to start this lol. In all seriousness I had an OK pregnancy, I had regular growth scans and they checked all the blood pressure through the placenta etc and all were fine. I was induced early in the end due to several episodes of reduced movements, I had an interesting induction but that's not related to the Low Papp-a.
All trusts seem to treat this differently but they will all have guidelines, I believe I wasn't allowed to go over 41 weeks and some places you cannot go over 40 weeks but I had nothing like the horror stories you hear about. I was already in slow labour when induced at 38+5 so maybe early labour was related? Not sure
There are definitely things you can do to help, look after yourself and eat correctly, keep stress low and just be on the ball with movements etc.
My blood pressure is naturally very low so I reached borderline for high (139 over something) and they wouldn't do anything but I had classic signs of PE. However being induced it probably wasn't a massive problem anyway.
I'm sorry I can't provide much more help than that, just rest assured that Low Papp-A shouldn't make you scared or anxious just be very aware that you could have these issues so stay vigilant as any pregnant women should be anyway.
I wish you a happy and healthy pregnancy! Please update this thread when you can and let us know, maybe if you have specific questions I could answer those? (Baby brain never disappears btw) lol
