What to expect at my first apt?

I called my doctor to schedule my first prenatal visit for March 15th, they don’t wanna see me till 8 weeks. They told me they are doing a intravaginal ultrasound and a culture swab for STDs. Will these hurt or just be uncomfortable. I just want to know what to expect.
