Finally made an appointment

Te

I've been TTC for a year and only fell pregnant once in march which ended in a early miscarriage with no luck since. I am the type of person who avoids the doctor at all cost and have severe anxiety when I do go or I usually end up cancelling the morning of but I vowed to myself and my husband that I will go to it. So with that being said, can anyone tell me what to expect from this appointment so I can prepare myself? Thank you in advance.
