You do need to get another referral if you want a 2nd opinion, but ring and make an appointment with the FS first as you are likely to wait longer for the FS appointment that than for the GP to get a referral. I think it's insane that an FS would not test for hormonal, physical or auto-immune issues, but using IVF as the 'test' to see if we get pregnant! It is important to remember that each of our situations and medical histories are different, but I find it so strange that we are expected to spend a small fortune each attempt of IVF, when testing would cost a fraction of the cost, just be be sure.

I would highly recommend making sure that the 2nd opinion is from someone that others value, and don't always rely on your GP's recommendation, my new GP didn't know what FET was so hardly think she has any idea who is a good FS! But I guess you will always be the best judge of character.
Goodluck to everyone waiting and I'll scoot back into my hibernation, watching and hoping for some BFP's in here very soon
