I finished radiation 4/30 and started Tamoxifen 5/10. Since having to stop birth control and go on the Tamoxifen I feel like a teenager again, in a bad way. Acne, awful cramps, emotional, unpredictable and heavy periods. There was mention of ovary suppression with injections, but my oncotype score was only 12. Has anyone else had a similar experience and/or done the injections or had their ovaries removed?
