Made our Fertility Consult Appointment...

Briana • Boy Girl Twins Born July 2018 at 32 Weeks after TTC since June 2015. MFI and APA syndrome. Had 4 IUIs and IVF fresh transfer prior to FET (2 early miscarriages from IUI and fresh transfer)
Made my appointment to start the whole fertility check process. It's been a year and I am nervous about what will happen. Those that have gone through it... Was it just a discussion and setting up testing or did the testing process start? I'm so nervous and scared. My doc suggested waiting til September even though it's been a year but I want to get the process started while my husband and I have the summer off (we're teachers) so I don't have to worry about taking time off for testing. Any advice, encouragement, or input would be appreciated.
