I hate be the odd one out here, but I'll tell my story anyway - I lost my little angel on the 29th of June 2007 and we decided to wait until August to TTC again, so we're in our 10th month of TTC and like you Lisa, my cycles are all over the place. Sometimes I get mine early, some times I get them super later. My last 4 cycles (including this one) were : 99 days, 23 days, 25 days and the current one is so far up to 35 days (with AF being due in 2 days according with when I O'ed and such)
I'm sorry if I wasn't much help, but I thought I'd share my story
