I'm 32 weeks pregnant exactly and I constantly feel like i can't breath. I feel extreamly out of breath. As if I'm only receiving half the amount of air that I'm inhaling. I could be sitting down not doing anything at all and I find myself gassping for air. My chest also feels a little tight when this happens. This does worry me because I'm afraid to sleep at night knowing that I feel this way during the time that I'm awake. Anyone has any suggestions on what I should do.
