I have been on bio-identical hormones for 2 years now. At age 39, I started having lots of problems with my menstrual cycle and hormones (Irregular periods, severe mood swings, fatigue, and brain fog).
Finally I found a doctor who agreed to check my hormones. My progesterone and testosterone were depleted (it was checked more than 1 time to confirm). Since then I started bioidentical hormones and my symptoms improved. I cannot stay without them as I tried and all my symptoms came back.
