Messy house frustrating

I am so frustrated with being unable to keep up with my house. My husband works all day but I had to quit my job because I'm high risk pregnancy. I'm so exhausted and have a hard time getting energy to clean my house at 25 weeks. My husband is kinda messy, but I feel bad because because college work (I'm an online strudent) and dinner, I don't have much to do besides keep the house clean and I can barely do that. Anyone else? Should I just not worry so much about my house?
