Uh.. hormonal changes can only do so much before it becomes an abnormal issue.

Depends on the person. I’m 33, I have for about 8 years had symptoms of early menopause, and yet every single test I’ve done (multiple per year) have cone back fine. I have spoken to multiple doctors, and have even fallen pregnant, and yet the symptoms continue. My headaches get so bad I cannot see and the only thing that kills it is time, or knocking my self out on heavy doses of pain medication for the same length of time. Not even s8 restricted level pain killers stop the pain, and this pain is caused by a cramping trapezius, that cramps up to a knot the size a golf ball in the back of my neck because of changes in hormone levels, for three days every month. And no they don’t know why my neck and shoulder muscles spasms on the last day of my period, for exactly three days, and has been doing so going on 4 years now. No amount of massage, neck adjustment, acupuncture etc has resolved it.

Or it could be a female who lucked out and got extremely mild menstruation symptoms.
