I just had the very same thing.My cycles have been all over the map, I once had my period twice in a month (another period just came out of no where when my husband and I went on a conceptionmoon) It has been totally working against me, I think it's been about eight months of ttc now. I have been off the pill for almost a year, and still I cannot get my cycles to be regular. For the first time since ttc, I had a 28 cycle!! My period came when it should, none of this four to seven days of brown spotting before my period...Dec 23 some light bright red spots..nothing more than a wipe, Dec 24, no real spotting..then on day 28 which was Dec 25 in the evening, I got my period. By the end of Dec 26th it seemed to taper off instead of continue in its heaviness...by the 27th it was all gone!!!! For the past week I have been hideous to live with, just always cranky!!!! When I don't eat I feel nauseated, but that is it. I can't take any of the hpt they all come out negative because my body just won't produce enough hormone. I went through that when I was pregnant in my twenties...none of the tests came out positive till I was eight weeks, but I knew they were wrong!!!! So, here I sit....waiting, irratable....confused.
