First prenatal appointment

What generally happens at the first prenatal appointment? I’m not really sure how far along I am (glow says 6 weeks but idk how accurate that is since my ovulation date was way way off from what the app says)

I’m a first time mom so I am a little clueless...I’ve read they confirm the pregnancy and talk to you, etc. but do they take any blood? And how much? 🤢
