I had regular menstrual cycles, almost to the exact day, until last month. My last period started Nov. 8 and it was on day 26 of my cycle, so I was due around Dec. 3. I have missed my period and have had intermittent cramping since the day I was due to start. I feel extremely bloated. I have no health insurance and am worried about how much the diagnostic testing would cost. Would a missed period be a sign of ovarian cancer? Thank you. DeAnne
