Extremely nauseous and tired

Just curious how everyone’s pregnancies differed from one another. With my first, I had a couple weeks with slight nausea, no vomiting. Now, with my second, I can barely move off of the couch. I’m extremely tired and nauseous. My house is a disaster, meals are whatever I can whip up quick and my poor toddler seems to be glued to the tv because I can’t find the energy to move. Any tips? Does it mean anything when two pregnancies are very different from one another?

Thank you :)
