anyone do housework during pregnancy

I very sensitive to smell so if I use any detergent or detol sanitizer etc I feel headache n nauseous. But I need to do housework like simple mopping floor once a week. How you guys do? Is there any fragrance-less floor detergent ? I can't mop whole house at one go so need to mop in parts n rest. Not like last time. Anyone experience same as me? I'm staying 5 room flat.
