Only 21 weeks and nesting like crazy!

I all of a sudden have a strong urge to organize/clean the entire house! I haven’t had the energy or urge to do this since I got pregnant. But now I almost feel guilty for not doing it! I am also having major anxiety about having the nursery done.. we’re in the process of painting it and I’ve been painting every chance I get just so I can put the crib up! I know I have plenty of time but I feel like time will be up quicker than I think. Anyone else nesting this early?
