Yeah I got this feeling last month. I think it's our way of protecting ourselves. We tell ourselves it wont happen so when it doesn't we'll be less disappointed- it doesn't work. I got very emotional when it didn't happen even though I knew deep down it wouldn't (it was our first month).
Also I think the first part of the cycle is easier. We are more in control, we can take vitamins, we can drink grapefruit juice, we can put our legs up etc. But once Ovulation happens, we can BD and then all we can do it wait....and the wait leave us with no control and no ability to do anything.
Keep your chin up, and try not to think about it too much. xx
