My period comes every 12 or 15 of the month, but last month I had dark blood on 6/5, and it continued to flow in the form of spots. I went to the gynecologist, and she told me that there is a cyst causing the blood flow, which means I stopped praying from 6/5 for a week. The doctor told me to take medication to eliminate the cyst, and I can pray since there is no menstrual blood in the uterus upon examination. What is the ruling on the days I missed prayer?
