I started using progesterone cream a couple of months ago when my period finally became so erratic that it lasted over a month, if only spotting, then started again, same thing. They have been erratic many other symptoms of perimenopause for about 10 years now, I turned 50 this year. I am so ready for it to all be over with completely. I can't use my mother as a reference as to when it will end because she finished up at 42! I couldn't have been that lucky. Anyway, the cream made period stop and cramps go away, but I wake up with a splitting headache when I've used it for several days and my ears ring loudly. If I don't use it for a day, the headache is gone when I wake up the next day. Can you advise?
