BFP nervous to tell husband?

So my husband and I have been TTC our second. Friday I was so nauseous and have been since. Had positive UPT for first response on Saturday and Sunday, and positive on clear blue digital today. So excited by nervous to tell my husband. Anyone else ever have this? I mean we were trying, and I’m not sure why I’m nervous. Should I wait longer to tell him? I’m I just crazy for not telling him.

I mean last time I was pregnant and showed him the stick he didn’t believe me... maybe that’s why?
