My shortness of breath during pregnancy turned out to be a pretty major iron deficiency but I had other symptoms as well - getting really dizzy quite suddenly and being so tired I needed to sleep all the time. I thought the shortness of breath was because I was really unfit turns out it was iron.

Worth talking to your doctor and finding out because it may be easy to fix.
i've had blood tests and my hemoglobin is 123

i have no idea if that is high or low, but the dr said it was fine. I do have iron tabs but they make me constipated so i havent been having them lately
