Hi Amanda

You're certainly in for a thrill ride. (Lots of ups and downs).
My partner (jeanette) and I have a three year old daughter and we are trying later this year for a sibling for her. We are using an unknown donor at the queensland fertility group. They are lifesavers
If you ever want to know anything about the process or the fertility group (or which doctors to go to) i would be happy to have a chat.
You can email me at jblee8278@bigpond.com

Good luck
Belinda
