I COMPLETELY understand. I was depressed for a while and TTC consumed my life. Looking back it was terrible what I was doing to myself emotionally. My friend Lori (she is on these boards) really helped me out so much and helped dig me out of the hole I was digging for myself. Now I am much more relaxed and happier about life in general.
There are ovulation charts online that you can use to perdict when you are supposed to o. They are not a science of course but only take a couple of minutes and can estimate for you. I use this one:

Well, with you being 8-9 dpo now, hopefully this will be your month and you will get a BFP! That would be awesome.
