I went through an ovulation induction cycle and was put on
prometrium (progesterone) to support a healthy lining. I am now 20 days past ovulation, no period, and three negative home pregnancy tests (it is now day 33 of my cycle and I am typically a 28 day cycle, like clockwork). I talked to the doctor today who told me to stop the prometrium and I should expect my period in 2-3 days.
