Cleaning while pregnant 😩😪

Today I am 20 weeks pregnant 🤰🏽 and at this moment I am taking a break from cleaning because I am so exhausted just from wiping a table and carrying items to the right room.. I literally just started the process and feel dizzy.. it’s freezing here in Mississippi and I have the air on because I didn’t want to overheat. I didn’t think it would be this tough, and I know I’m 3 1/2 months I’ll be going they something more exhausting than this. Any tips on getting it done? Without too many breaks?
