I'm 33 weeks pregnant. When I wake up in the middle of the night, I feel like I can't breathe. I'm ok after taking a few of deep breaths. The first breath is the most difficult tho. I'm not really sure if this is normal. I feel like it might be because I'm taking some classes and the teacher said the further along you are the more difficult it is to breath b/c there is pressure on the lungs. I have difficulty sleeping as it is, it just makes it worse worrying that my baby isn't getting enough oxygen if there is in fact something wrong with the way I'm breathing while I sleep. I don't know. I thought I'd ask some other pregos :) We're all going through the same thing.
