Has anyone had a dull pain in your chest? Pregnant or not? I've had it for about the past 3 hours and it kinda goes from arm pit to arm pit. It's not TERRIBLE pain but it's there and anytime I get up to do something it gets worse, I start breathing heavy and I have to sit down :( For example earlier around 6:30 I got up to make supper and I made it to the kitchen and got the pan out then I had to sit down. Any advice?
