Paperclip, if it helps I remember my appt is like :
1) first appt with doc, that day itself I take blood test
2) half a day for pre test scanning
3) half day to see doc and review all the results and he say go for ivf
4) half a day for ivf briefing (ivf needs to do 4 blood test. I did it separately at GP and pass to them during my mockup)
5) half day for mock ET (my doc ordered that so I have an additional step)
I didn't take long to consider because of my age and my age probability is also lower. I just go of it and the rest should follows

be positive k
Now day 5 of my injection. =)
