I was told some people may continue to have a period while taking it and others may not.
I started Tamoxifen and after having irregular bleeding (twice a month) and also pelvic pain, my Gynecologist did a pelvic ultrasound and I had a uterine fibroid, a large cyst on my left ovary and my uterine lining was a bit thickened.
I am now 3 weeks out after having a total hysterectomy.
If you feel the bleeding is something new, definitely wouldn’t hurt to ask your Gynecologist.
