First Appointment!!!

Hello loves, so I just found out I’m pregnant yesterday and called in today to make my first appointment and for my first appointment I’ll be 6w3d I thought that was a little early. I’m also 17 so are there any girls who got their appointment that early and what they saw ? I’ve also been having cramps on and off and lower back pain and hip pain that shoots down to my legs which Idk if it’s normal? Right now I’m 5w4d.
