Hi Dr. Iam On A Petrogen And Ever Since I

Hi Dr. Iam on a petrogen and ever since I started with it have been having regular periods 2-3 weeks in raw with one week of break. I went to see a doctor and she told me that my hormones are reacting so strong. She then gave yet another injection but this time with pills to have for 28 days. My periods stop completely but 3 days after that 28 days of taking the pills my periods started again. Can this be a sign of something not good for my health?
