Hello,
The importance of regulating your menstrual cycle is to prevent the inside lining of your uterus (the endometrium) from prolonged exposure to unopposed estrogen. Prolonged endometrial exposure to the uterine lining in the absence of progesterone can result in endometrial tissue overgrowth (hyperplasia) and the development of abnormal tissue (atypia). In your case I assume your physician believes your absence of menses (amenorrhea) is the result of not ovulating (anovulation). Anovulation can be the result of pregnancy, hormone changes to Thyroid hormone (TSH) or Prolactin, physical or emotional stressor, and commonly a condition called polycystic ovarian syndrome.
When a woman does not ovulate she does not make the necessary levels of progesterone to protect the endometrium.
Now, there are many ways to regulate the menses and/or to supplement a woman with progesterone. You have been prescribed progesterone only pills, which is fine. A Mirena IUD and Depo Provera are other alternatives, again, if available. You could also start a estrogen/progesterone containing birth control pill (or alternatives available in your country) if you have no medical contraindications. What has been recommended by your doctor sounds fine. There are side effects to all hormonal contraception. Talk this over more with your doctor. But you are okay to take what you have been prescribed.
Best regards,
Dr. Downing
I believe I was told I have PCOS. If I want to get pregnant is this a good drug to take, or will I need to switch drugs to something else before I want to get pregnant. Should I ask for drug specifically? any recommendations for pregnancy with PCOS where you need a high dose of progesteron to regulate your periods.
