Chrissy, sorry you're feeling so down about TTC at the moment. I know it's hard and some months are worse than others. I find when I am busy and have a lot of stuff on, the cycles fly by and it doesn't have a huge effect on me. Then come those months when you have too much time on your hands and your mind starts going a million miles an hour over TTC etc.. IVF, as I have just discovered, is a whole other kettle of fish.
I hope your BFP is just around the corner....when you're so busy with xmas that you don't realise AF is a week late, and when you do, you get that lovely 2nd pink line on your HPT!
