No worries, I know how busy kid life is and mine are young! I am wondering the same thing, when my periods are normal will I be? I generally am ok on my period, but ovulation is terrible, I have cramps, back pain and headaches. I had never had that before the mirena, I couldn't even tell when I was ovulating, now, however I am so sensative to what my body feels and I do not miss a beat.
Definately let me know if you find any information about the cycles, I do not have a yearly for a while , I had one 2 weeks after I had the mirena removed to make sure I had to cysts, or tears on my uterus. I hope you are well, take care and I will e-mail your personal account soon too.
