Was at the doctors the other day my anxiety was pretty high and i felt a panic attack on the way. They took my O2 levels and ot was at 94%...whitch caused me to freak out terribly. They didnt seem to alarmed...but what would cause a slightly low reading? I was not wearing nailpolish or anything. I was short of breath but mainly from anxiety...i got beat red in the face and felt like fainting. Im only 19 and 29 weeks pregnant. Someone ease my mind! I think i am going to buy a pulse ox for home. Im to scared to go back to the dr to recheck it! :( is this to low of a reading?
