How concerned should I be with periods restarting after 3 years of none while on tamoxifen? I was diagnosed with stage 2 infiltrating ductal carcinoma over 3 years ago, ER +, her2neu+, had taxotere and carboplatin x6 rounds, and a year of herceptin. Am on tamoxifen x3 years, and have not menstruated since I started chemo, so over 3 years. I am 47. Just started menstruating yesterday, and was a little shocked! Any thoughts on this?
