When should we schedule our first dr appointment?

I'm 4 weeks, feel like mute point to schedule it so early. I was thinking to wait until week 6 at least but hear sometimes Dr's say until week 8. What at you mamas thinking? Ps I'll admit I'm nervous about going to the Dr's I really don't want all tests & think pregnancy had become big business...def doing a birthing center instead of hospital so may need to switch to a holistic provider!
