Should I say something to my MIL/husband?

So this might sound so dramatic lol, But I have to do a little explaining first. My husband and I live just a few houses away from his parents, but we both work a little over an hour away. So Tuesday-Friday for me and Thursday for him, we stay at my parents house. While we are away, my in laws watch our chihuahua (he doesn’t like going to my parents because of their dog and he ADORES my MIL) and she will occasionally stop at our house to check our oil, water Xmas tree etc. so our house is really really old and not nice. We are tearing down and trying to rebuild, at the same time I am pregnant and my husband is a bit stressed with work. So it gets a bit dirty with papers, laundry isn’t always done and constantly getting dusty.

ANYWAYS, this week I came home and all of our laundry was done by my MIL. But for some reason it bothers me. I know it shouldn’t and I feel soooo bad feeling this way because she is so sweet and just trying to help, but it makes me feel weird knowing she’s going through our dirty clothes and folding it and what not, mind you I’m annoyingly picky about the way my clothes are done.

Should I say something to my husband and have him mention to her that she doesn’t need to do it? I know I might sound ridiculous to some of you and I soo do appreciate her thinking of us, but it’s just odd to me!
