Nesting x100

I am only 5 weeks and want to clean everything and sort through things we need and don’t need. I also want to get the nursery set up but I feel like it’s way too early. We don’t know the gender or anything. Never had a true doctors appointment and I don’t even really feel pregnant. The only thing I’ve gotten was multiple positive confirmed tests. This is going to be my second. I hate feeling this way when I can’t do anything about it. I need some ideas to pass the time. Where are your fav places to make a baby registry? What are your must have baby items? What are your fav nursery themes for boys and girls? Also fav crib, car seat, and places to buy baby clothes? Any advice and suggestions are greatly appreciated!
