I am nearly at the end of my cycle, but just discovered last Friday that if I went to the nearby hospital for my E2 & P4, they just ran it through my insurance company as "diagnostic/screening labs" and not "infertility" so it will be covered. Also, I don't even need an appointment. I can just walk in. Had zero waiting time the other day. I'm going to go there for my betas as well. They process the results in about an hour or so which is even faster than the fertility office I was going to. Wish I discovered this option sooner. Best of luck to you on your cycle!
