Excited!!

I am 4 weeks & 6 days.my first pregnancy. I just wanted to ask if anyone else feels slightly gulity about getting excited because its such early days? Apart of me just wants to tell the whole world but the other part is thinking, no calm down its far to early! I'm trying to be positive but understand there can be complications also?! Am i crazy?! Is it to early to be excited?💖💙✨
