Question?

I just wanted some opinions as to when would be a good time to call my Dr. to report that I'm pregnant? I got my BFP this morning at 11 DPO so I was thinking maybe after I actually miss my period? It's hard for me to say when that will be because I came off BCP in August and haven't had a steady cycle yet. Last month I went 37 CD before starting and the month before I went 33 CD before starting. Glow predicted Friday and Ovia predicted Sunday. Just curious, thank you :)
