When to make an appt

When are you making your first appt.. I'm 5 weeks and 5 days and I feel like there really isn't any reason to make one just yet... What's the point of the early appointments?? I've had two kids and with my first I didn't find out til 34 weeks and with my second I found out at 4 weeks and 2 days and I feel like my first few spots were just pointless with my second one they didn't test my hcg levels, no ultrasounds, just peeing in a cup and getting zofran and monitoring weight loss.. so is there a point to them that I'm just not getting?
