am I late going to the doctor?

Savannah
first time mommy here! im 5 weeks and 1 day along. I found out I was pregnant 3 days ago and ive just let it soak in. I've been taking prenatals the past month (hubby and I were trying) and I'm currently still taking them now that I know I'm expecting. should I call the doctor tomorrow? how far along do you have to be for them have you come in? for some reason I feel guilty I didn't notice I was pregnant sooner and get to the doctor sooner!
