a bad day

I would like to find out from other's that have done or planned to do IVF what did you do to prepare your body and when did you start because I have done a bit of research and I am scared that I have not done enough as I am seeing my doctor on Thursday (AF to come the weekend) so that I can go on BCP and start IVF early Oct. I am now getting cold feet and scared sh#$@less and I am getting nightmares about going for ER but that I have forgotten to take the trigger shot (like I will let that happen) but they still did the harvest but then the embriologist was cross because there were to many eggs like WTF. I have done this 4 times including the FET's and I have never had the dreams.I am at a cross road and need a map or a magic GPS to tell me where to go what to do when to do it. I can't share this with anyone as I want to keep this between myself and DH so I only have my computer friens on OPM to talk to.I do not feel capable and emotionally strong enough to wait another three months either.I am lost please help !!!
