I had a vaginal hysterectomy in 98 and kept my ovaries. I've had no problems for 18 years, but suddenly am having cramps like menstrual cramps. This morning I was woke up by cramps, and had some slight spotting when I went to the bathroom. I can't go to the dr. for 3 months because I'm waiting for my insurance to be reinstated after having had to appeal. I cannot afford a doctor right now. What could cause this? I'm 62 yrs. old.
