@rosehaven I think it depends on your age as in where you are in terms of menopause and how far away that is. I was on Tamoxifen for 4yrs from age 43, I had a period every month but it was quite light and only last about 4days. In 2015 I had a recurrence and pulled off Tamoxifen, had treatment Chemo no rads as I had that 2011 and now on Arimidex. So I think it sounds normal. :) Oh but thrown into menopause in 2015 from chemo I'm 48..so no period uuugh which is worse I feel LOL and feel this is where the weight comes from menopause lol.
