I am now 14 weeks pregnant from a FET cycle at Cooper, my fresh cycle didn't work.
The only time I ever saw or talked to a Dr during the cycles was at the transfer. Dr Brasil did my first transfer and Dr Cho did the second.
After going in for blood and US's, I would get a call from Terri, the DE coordinator, with my instructions.
Actually, I did also see Dr Brasil for my sonohysterogram that I had before the fresh cycle started.
