Hi Jenny,
Next week will be 3yrs since diagnosis for me.
I was 39.
The chemo put me straight into menopause and I have struggled with up to 50 flushes a day. I am currently on a natural product 'Menopause Free' which is helping (now only 4-8 flushes a day & not prolonged). The brand is Fusion Health. I found I couldn't tolerate the black cohosh version as it gave me awful headaches.
I have had my hormone levels tested post-chemo & am having some ovarian activity, so they weren't obliterated.
I had a hysterectomy at 33 (other problem) so it's a bit different for me as no periods to gauge from.
My doctors can't give me a definite duration for this menopause thing so I'm just dealing with it. I don't want to take any prescription drugs (my bc was triple neg so I do have options). I just going with whatever:oP
Good luck & blessings
Sam
