Hi Beth
I have found the ladies in here to be very supportive & helpful. You could also join a chatter thread that suits your situation. They are in the conception & LTTTC section.
I hope you can find all the help you need here
While weight loss is a proven remedy, there are definitely other things your FS could do in the meantime esp after nearly 2 years of trying. I can't help with a Brisbane FS but I could recommend one on the Sunshine Coast.
