Tina,
I did 12 months of clomid and that seemed to be alot more emotionally draining on my me.The change over to IVF was good as it incorporated DH more in the process as my fertility doctor had never met my DH in all the 12 months of clomid and on my first IVF pick up he actually got to experience all the up's and downs I had done alone for 12 months. I found it was good that DH was always positive on cycles and many times he was the one that saw the "big picture" that was fading for us.
I would not know how much it has costs us all up and often we laugh about our many trips overseas and new cars we could have bought but the outcome of our daughter is far better than driving flashy cars and stamps in our passport.
I hope the clomid works this cycle and if not the IVF journey is short and sweet.
Bec
