When did you start nesting?

I will be 7 weeks tomorrow and I found out at 4 weeks. This is our first baby and we've been trying for this baby for 5 years. As soon as I found out I was pregnant I got the overwhelming need to start buying everything right away. We just started the remodel for our nursery and I don't want to buy the furniture until it's finished but it's killing me not to! I don't want to go out and buy a bunch of stuff before my shower either but I feel like I need to! Why do I feel like nesting so bad already and I'm only 7 weeks?! 😭
