When is it too early to buy baby things?

so i haven't bought anything yet, and i am not pregnant, though trying. just curious what people's thoughts were about buying things like baby furniture early on. i know my mom says you dont want to buy before first trimester, some say later, just in case something happens or you end up not being able to have kids. i personally like to be prepared for things so i kind of wanted to buy things early, again talking mainly furniture. i also feel like if the worst scenario happened, we could always give the items to charity or something. I'm not saying the things would be set up but at least we would have them and not have to worry about being able to afford them when i actually am pregnant. idk, am i weird? Lol
