Hi , I'm A 57 Year Old Female In Menopause.

Hi , I'm a 57 year old female in menopause. I have had hot flashes for about 5 -6 years. I exercise vigorously twice weekly and work full time. I'm fatigued much of the time though. I am on a 0.075 mg estradiol patch. Is this safe for me and do you have a recommendations to combat this fatigue? Thank you.
