Helen,
Thank you so much for your input. I will start calling the Doctor's office daily to check for cancellations. They do not keep a cancellation list anymore.
So far the spotting is intermittent and with it comes the heavy feeling in my lower abdomen that use to warn me that my menstrual period was about to begin.
I will reduce my estriol dose for now. My Aunt had a hysterectomy in her 30's which was hush, hush. Hopefully I can find out why from my cousin.
