I'm in the middle of checks to see whether I have got a 'PE'. Had a positive blood test (di-dimer as it is called) but apparently that is not conclusive as preg. women often test positive, had negative blood gas check and negative or inconclusive chest x-ray. Now they want to do a 'perfusion scan' (rather than a CT scan as less radiation)to see if that shows anything. I am just under 38 weeks - so so nearly there, I'm on Klexane to thin the blood as a propholaxis (sp). Pain in chest on deep breaths and related to some movement but not any obvious bruising or injury to connect it to, no more than normally short of breath. Sad. Anyone got any similar stories?
