Can the uterus grow rapidly overnight?

I was feeling fine yesterday morning but around halfway through the day I just randomly started getting shortness of breath. Like worse than I've ever had before. I also felt sick (like nauseous w/ headache) but I think that was because of something else.

Today I feel fine aside from breathing difficulties. And I noticed towards the end of today that the bottom of my uterus feels really tender. Is it possible that it had a little "growth spurt"? (for lack of a better term)
