First pregnancy

I will be 33 tomorrow. I took two pregnancy test a few days ago that both came back positive. I maybe a doctors appointment but they said I can't come in until am 8-9 weeks. Right now they think am only 4 weeks. I spoke to other people in my family who have children and they think that strange I have to wait that long. Because, I'm new to this I would like to see the doctor right away just to confirm 100% that am pregnant and just check on things. Has anyone been told they have to wait 8 weeks to get your first check up.
