Shortness of breath?

Andrea

Hey all! I'm appx 7 dpo, got on the stair climber to do my cardio and 4 minutes in got SUPER winded- I'm usually able to do 20 minutes before I'm done and I never feel like that. I'm a trainer so this is extra weird for me.

I've also noticed a major increase in cm... I guess I'm just wondering if this is all in my head or if anyone else has experienced this as a possible early sign?
