I just turned 13 weeks and I have been cleaning houses since I found out I was pregnant. Lately i have been having to clean them by myself because my boss goes to other houses to clean. Now these are big 2 or 3 story houses. I have to climb the stairs with a backpack vacuum or a regular vacuum several times a day up and down. It makes me dizzy and out of breath to where I have to sit down for awhile. I tried going to my doctor for a "light duty" note but they haven't called me bAck. I am on the verge of quitting if I can't do less work. Does anyone have any advice? Try and stick it out with the note? Or quit? I don't want to do anything to harm myself or the baby but I'm not sure if it is to early.
