abbey, thats a coincedence you should mention about shortness of breath..i posted on the 'pregnancy' thread earlier asking just this..
i was soooo out of breath this morning, i cried myself with worry, and then an hour later, postman had been and theres a note from hospital regarding my antenatal appt, and the bloods have come back showing im low in iron
one quick call to doctors and i am now on iron tablets.
have you had your bloods taken to check for iron? i remember my sister in law being out of breath that she couldnt get enough oxygen and she insisted they check her iron level even though she wasnt in her 3rd trimester, reluctantly they took it, followed by an emergency call for her to get to surgery asap as she was very very low on iron!
have your iron checked out if you havent done so already and insist they do it! thats my advice
