I was given a Progesterone test by my doctor on August 19 and it showed negative results so I was told to start taking Provera on August 20. I took 10 days of the Provera and finished my last dose on August 29. I still have not started bleeding so I took a pregnancy test today and it came back positive. If I am pregnant then I was only about a week pregnant at the time of the progesterone test.
