And it starts again

I started lupron shots 3 days ago. Woke up this morning with a headache. I was hoping the headaches wouldn't start for at least a week or more. I read blogs from other women who seem to have so much more faith about their cycles working than I do. I wish I could go back to the days when I thought I would get preggy from cycle number 1, with twins of course. Instead I'm sure the cycle won't work, even before it begins.
