OB GYN Appointment

I called the doctor's clinic yesterday to make appointment for my prenatal check up. I was hoping to be able to see my OB-GYN as soon as possible because I'm a little bit paranoid when I found out I'm pregnant because of the previous miscarriage I had but the nurse said that I have to wait until I get 7 weeks of my pregnancy before I could see my OB-GYN to have an ultrasound to check if there's a heartbeat. So my first check up will be on Nov. 14th. For now I just have to wait and hope that the fetus will normally develop and will find heartbeat once I get my ultrasound.
