Anyone else tired of getting out of breath so quickly?

Tomorrow marks the start of my third trimester, and man, fatigue is definitely trying to come back with a bang. It's now also accompanied by shortness of breath. Seriously! You'd think I'd just come back from a run, but no, I've only gotten in from carrying in the groceries! Even changing the bed sheets is a challenge. Like hold on, I need a 5 minute sit in between the fitted sheet and the flat sheet lol.
