Need some advice! Help!

I need some advice ladies. I'm currently 33w/3d. I am scheduled for a c-section at 36 weeks on December 28th. So as you can imagine, I'm super uncomfortable, but still trying to make it through my ridiculous "to do" list. I also have 2 toddlers, so the daily cleaning alone is nearly killing me. With all of that being said; my husband invites his brother over pretty much every night that he isn't working. Which is usually 4-5 nights a week. He eats dinner here and all that. The issue is, he doesn't really clean up after himself. When he goes to the bathroom, he pees everywhere. When he eats dinner here, it causes more dishes. We don't have a dishwasher. I'm just upset that my husband hasn't realized how much extra work this actually is for me. It may not seem like a lot, but it is when you already can't move. How do I bring this up to my husband, without sounding like a total b****?
