Totally exhausted

Anyone else in the beginning of their pregnancy just feel totally exhausted and have no motivation to do anything?? Ughhh I hate this feeling of knowing so much needs to be done but not feeling like doing anything! I'm worried it's going to be a lot harder when the baby comes :( and we still have so much to do in the upcoming months with switching our oldest two to the same bedroom and redecorating two bedrooms. As if I don't already have enough laundry to do all the time, we decided to add another clothing wearing human to the mix? lol what was I thinking?? (that's totally a joke, we wanted this baby I'm just freaking myself out) but for reeeaalll. goodness I'm so tired and don't wanna do a dang thing but nap :'( how'd you mama's push through this feeling? any tips on keeping a clean home??
