I'm only 10 weeks pregnant with DC3 and I'm experiencing the same symptoms I did with my previous 2 pregnancies - nausea, fatigue, etc, but once or twice a day I get really breathless - even if I'm lying in bed doing nothing! It only lasts for a few minutes, but my chest feels really tight as though I can't get enough oxygen. I know this is normal very late on when baby is squashing everything and pressing on lungs, but at 10 weeks?! Is that normal?
