BC after taking Fibristal aka Esmya aka ulipristal acetate

There is a relatively new drug on the market to treat uterine fibroids called Ella in the US and Fibristal in Canada. It is a selective progesterone receptor modulator. In the UK its trade name is Esmya, and the pharmaceutical name is ulipristal acetate. I was diagnosed with breast cancer after taking a 3 month course of this drug. I took the drug immediately after having a breast MRI for screening purposes that was clear. Six months after MRI number 1, I had a second MRI which revealed my tumour. In my case, because I was being closely monitored by MRI, we know with certainty that the tumour appeared shortly after taking this drug. Has anyone else had this happen to them? If so, please include the type of breast cancer with which you were diagnosed.

I think that the regulators (FDA, Health Canada, etc.) may need to take a closer look at Fibristal to determine whether it causes breast cancer.
