First time being pregnant - advice needed

Hey everyone. This is my first time being pregnant and my husband and I have not yet told anyone with the exception of some work friends because we’re together too much for them not to figure it out on their own. I’m doing tons of research but dying to hear about people’s true experiences. Can anyone please tell me what to expect on the first prenatal appointment?? I still get nervous that I’m not actually pregnant even after taking 4 positive tests. I’m apparently 6 weeks and 1 day based on this app. My symptoms have really just been extreme thirst, frequent trips to the bathroom, and light cramping and bloating here and there. I always assumed I’d be throwing up or something. Just trying not to panic or think the worst.
