I Took An Ovulation Cycle Day 13 And It Came

I took an ovulation cycle day 13 and it came out positive. Two weeks later I got my period. But three days after I ovulated I got blood work done. One week later we went over the blood work and the doctor told me that I did not ovulate. I have cysts in my ovaries but my cycles are usually 25-30 days long . Most of the time 27 .
