I'm 27 weeks' pregnant and for the last few weeks have been increasingly breathless.
I thought initially that it was just getting more puffed out while walking/stair climbing etc but it seems now to be graduating to random attacks of breathlessness - like just now, sitting and MNing at the computer, I found myself heavy breathing.
The worst was the night before last when I was woken up four or five times from deep sleep, completely out of breath (like I'd been running) and my heart racing. It was quite scary actually.
Has this happened to anyone else? Am just trying to work out whether it is normal run-of-the-mill pregnancy fun, or something I need to see my doctor about.
