Tamoxifen and endometrial thickening

Hi I had my last period about 18 months ago and was diagnosed with bc in may this year .i started tamoxifen about 3 months ago and I’ve been having cycles of dragging ,like period pains but no bleeding then they seem to ease ,almost like I’m having periods still without the bleeding .i went to have an ultra sound this week and the radiographer said I had thickening of my endometrium , being a nurse I went straight on the Internet and researched what this can mean and wish I hadn’t!! It is associated with tamoxifen and I thought that after 3 months there wouldn’t be changes ? Am I wrong? Or is this a problem that may have been there already ? I’ve got 5 years on the tamoxifen and I really don’t want to put myself at risk of endometrial cancer , anyone experienced any of this ?

Bizarrely the first period on tamo arrived early, then the next one a bit late. V odd period, lower abdomen felt v swollen and would bleed for a few hours, then nothing (at all) for a few hours, then bleed again. Also had a rather unpleasant lump of jelly like blood appear.
Is this the type of impact on periods others have found re tamoxifen? And if so what tends to happen re length and frequency of periods going forwards?
Interested in hearing others experiences re what i might expect next
