low Papp-a

katie
hi ladies! 
I just had my first trimester screening and the NT came back negative but I had low levels for Papp-A. normal level is 0.4 and my level was 0.29.   the nurse said these low levels mean there could a chance for preeclampsia, low birth weight or pre term labor.  I'm trying really, really hard not to google it so I don't scare myself. so really, I'm just asking for success stories? if there are any. if anybody had low levels in a previous pregnancy and were fine? thank you in advance for any help!
