Hi Snowie - I find it incredulous that testing is not being offered to you after 3 consecutive losses, such as you have experienced.
Call QFG (Qld Fertility Group) on Wickham Terrace, and enquire as to whether DR WARREN DE AMBROSIS is back from leave yet. He is very aggressive in his management - will be entirely upfront with you - and is a big softie underneath the rugged exterior. He is extremely knowledgeable and I trust him immensely in all gynae matters.
(If you do not have any luck getting into Warren - ie, if he still on leave - PM me - and I will suggest some other names. He would be my first port of call though.)

Thinking of you - Tracy (Brisbane)
