I am 45 had similar symptoms as you, diarrhea,shorter periods, migranes, fatigue etc and I thougth it could be the start of menopause. It turns out I have hyperthyroidism. A simple blood test would be able to tell you this. Take Care and Good Luck
Update:my ob/gyn ordered 4 tests. FSH/LH levels, TSH, E2, and progesterone. Anyone with comments on this? Anything anyone has to offer would be greatly appreciated. Thank you.
There is an FDA-approved self-test that measures the level of FSH in a urine sample. It is used as an indicator of perimenopause, which is associated with a rise in FSH levels. For more information, visit the FDA
