Hi SaraR
Sorry to hear that you missed a date, however as Spacial said, "At least it's going to happen.", and you know the date. Time will fly by and before you know it, you will be a 'New Women'.
I remember asking my surgeon for a date and I was given one (3 days before my birthday, what a bummer), however I was to busy working and enjoying life that I did not count down the days until my surgery.
In regards to blood tests the only one that I can remember having that was a prerequisite for surgery was the HIV one. This was in 1991 and if you were HIV positive, then you could forget about surgery at the time.
Being deflowered one year later after my surgery is going to be one night I will never ever forget.
Take care and all the best for the future.
Kind regards
Sarah B
