Three weeks of continuous bleeding is definitely something worth flagging with your doctor right away — don't wait until the scan next week. While heavy and irregular periods are a known side effect of tamoxifen, prolonged bleeding like this needs to be evaluated promptly.
You are absolutely not alone in this experience. Many MyBCTeam members have shared similar stories, with one describing cramps as "terribly painful" and periods being "just heavier overall." Another shared that their periods were so heavy they became anemic. Here's why it's important to get this checked out soon:
- Prolonged heavy bleeding can lead to anemia, causing fatigue, dizziness, weakness, and nausea
- Bleeding changes can sometimes signal uterine changes like polyps, fibroids, or thickening of the uterine lining
- Your doctor may want to rule out anything more serious given your breast cancer history
The good news is there are options to help manage heavy bleeding, including certain types of IUDs that are safe to use alongside tamoxifen.
Please reach out to your oncologist or gynecologist today rather than waiting — three weeks of heavy bleeding deserves immediate attention. 💛
