I'm 53 and have been using progesterone cream for 5 months. At first it seemed to help with my hot flashes but recently they seem to be getting bad again. I've increased the dose to 400 mg a day and have been doing this for over a week and its not helping. I'm confused because ive read that if they start up again to increase amount used which I did but its not working. What should I do? Does this mean its not gonna work for me & should I quit using?
