Hi Elzi
We started ivf/icsi in June (we actually started in March but I fainted, broke my ankle and had to have the cycle cancelled!!)
I thought getting PG would be easy and never thought I would be doing all this. I was scared about the injections too and I found the best way for me to cope was to get DH to administer (which he does not mind doing and does really well!) they do not hurt. As for the dose it is a little hit & miss, my first cycle when I went for my first scan nothing was happening so FS upped the does and I ended up being overstimulated and got too many eggs. 2nd cycle I was on a lower dose but still got overstimulated. Both times after egg pick up I was told it was cancelled and would be freeze all BUT each time I saw the FS and she checked me out and was happy that I had recovered and was able to do transfer. This cycle we are doing an antagonist cycle. My FS only tranfers 5 day blasts so I do not know about the day 3 issue.
Its not scary once you get started, for me the worst thing is the ups & downs (being told its a freeze all and being let down, then transfer going ahead etc...) other than that the tww is the worst part I find and of course coping with the let down when you are not pg.
Good luck with everything
