I'm 8DPO or thereabouts and know I'm not pregnant because this PMS is horrendous! I feel sick, headachy, miserable, and have already yelled twice today at the kids! I never get this when I'm actually pregnant so having it convinces me I'm not and further adds to my feeling that I'm infertile after mirena! I just want to this day to be over, I am NOT in the mood for being cheerful and merry....[hmm][hmm][hmm]
