IVF NJ - RMA vs. IRMS

Hi everyone. I'm 31 years old, and my wife and I have been going to IRMS to try to have our first child. I have no known fertility issues. We tried IUI first. The first time it resulted in a biochemical pregnancy. The next three IUIs were unsuccessful. We then just finished our first IVF attempt. 25 or so eggs were retrieved, 9 were fertilized, and after genetic testing, 1 was "perfect" and 1 had low mosaic. We transferred the "perfect" one and it implanted, and I was pregnant until miscarrying right around my fifth week. We are worried because we only have two more covered IVF cycles with insurance. Should we switch to RMA? We love the doctors and nurses at IRMS, but are wondering if we would have more success somewhere else. Is there a place we can find success rates of RMA vs IRMS? Thank you for any advice.
