Stressing here anyone ever had d dimer levels elevated ?

Thlyaa

my previous pregnancies I didn’t have any issues like this but doctors have me stressed out saying my d dimer leveled were elevated but they did c t scan & x rays etc & they said everything was normal but they sent me to see a cardiologist to make sure my heart isn’t enlarged idk why they said that but something about my blood work showed my level elevated but I thought during pregnancy your levels can elevate am I wrong & why would they stress me out like this if they said they found nothing abnormal with the other results so I basically have to have an echo done but I don’t even think doctors know much at this point why they have me running around in circles stressing me out
