NYC Fertility Clinic Recommendation

I have been going to CNY for approximately 7 months and unfortunately have not had any pregnancy success. I question whether I need further testing (who am I to know, but I can’t help but worry.) I am 30 years old, have been told I have PCOS and have NEVER achieved a pregnancy. My husband and I are considering traveling to the NYC area, but there are SOOO many clinics how do you choose!? I would appreciate any recommendations! I don’t know what is considered “good insurance” but I would say our insurance is okay. Thank you!
