Why Do I Love Cleaning During Pregnancy but Dread It Otherwise?

How is it that at 20+ weeks pregnant I lovee scrubbing the floor 😂 dread deep cleaning day when I'm not pregnant.. But once I am well into my second trimester I love cleaning. Well correction I love cleaning with pinsol and Lysol lol. I know there's the thing called pica or whatever but I take all my vitamins and eat well. Still love the smell of a clean house more than anything 😍
