Welcome to BB!
I'm sorry, I can't give you much advice about the IVF treatment, but I can tell you that you have certainly come to the right place! We've got a few ladies here who are travelling that difficult road, and I hope they'll pop their heads in to give you some encouragement. Have a look through the journal section, and you'll find a few in similar circumstances, I think.
Hang in there honey - you can do it!
