Hi Beark,
Welcome to BB, I am fairly new myself, there is a link that says abbreviations, if I knew how I would put the link here, but just have a search? You will come across it....eventually? If I found it, you can certainly find it!
Regarding your IVF treatment, I can share my journey with you, with both clinics. When we found out we had to go through IVF, we first went with Westmead, they were nice, I wasnt unhappy with them, but I didnt love them either, 18 months later and 3 failed attempts, I had had enough and my DH and I switched to SIVF, and I could not be happier, I actually recieved my BFP with them for the first time, but unfortunatley I miscarried. There are a few things that both clinics do differently (in my experience anyway), Westmead use synarel (a nose spray) & puregon injections while SIVF use puregon & lurin injections with no spray. I prefered 2 have both injections instead of the spray, I actually hated it, it was horrible. My experience with Westmead was that I felt like a number, a process line, there was nothing personable about them and there was a bit of waiting around because they are so busy & SIVF were beautiful, very comforting very personable, I will not be going back to Westmead, (to be honest, I like a bit of hand holding and SIVF do that) having said that though, SIVF are MUCH more expensive than Westmead so it also depends on your financial status. I dont know though about Orange SIVF??? I go to Baulkham Hills SIVF & they are great.
Everyone has different experiences, all I can say is if you are not happy with the clinic you have chosen dont be afraid to change, this is a very trying, personal journey for both you & your DH, go with the one you feel most comfortable with.
I wish you all the best on your journey.....
