Advice Please!

So based on my LMP, I turned 5 weeks yesterday. (I have no idea when I ovulated, as I wasn't tracking much this month to give myself a mental break.)

I called my doctor's office yesterday to schedule my first appointment and what I thought was going to be closer to 8 weeks, was actually scheduled for Thursday!

Have any of you ladies had an early appointment? Any idea of what I should expect? I'm assuming with my miscarriage in July, they'll do bloodwork, but I'm trying to figure out what else could be done or checked so early?

I'm stressing myself out. I just want this to be our rainbow baby so badly!
