1st prenatal visit

Ti
First time mommy here. This is my first pregnancy and I'm just wondering what all happens at the first prenatal checkup? I'll be 5wks2ds on the day of my appointment. Appointment date set for 6/28. Will they do blood work to check my hcg levels? And how soon until I can get an ultra sound? I'm totality excited and any info will help.
Thanks in advance :)
