controlling and a perfectionist

I'm not a mom yet. I feel like I need to take care of everything and the house has to be spotless all of the time. And it's worrying me a little because I know I won't have a lot of time when I do get pregnant to keep up the house and stuff like I do now. It literally stresses me so much when things are out of place Or out of a normal routine. How do you deal with it?
