Can you ask to be referred to a menopause/gynaecology clinic. Sometimes the two cross over. I was given progesterone suppositories in my 30s for PMT by my GP. Personally, I didn't find it helpful but then I had suffered with dysmenorrhea and PMT since starting periods. Katharina Dalton was a doctor who believed that progesterone helped PMS because women did not suffer with PMS migraines when they were pregnant and producing high levels of this hormone. She wrote a book called 'The PMS Bible" It does help some. I believe the mirena coil works by releasing progestogen which is the synthetic version of progesterone. It stops your periods too. My friend has one, and it has made a terrific difference to her life. Maybe its a case of trying it, but making sure they would remove it if any problems?
Although menopause has its problems, I am suffering less now without the monthly curse!
