Kept my ovaries for now, but going through perimenopause. Estrogen question.

Last year I had a hysterectomy and had my tubes removed as a preventative measure due to the BRCA mutation. However, being in my mid-forties, I’m starting to experience perimenopause symptoms.

As a mutation carrier with my ovaries still intact and pre-mastectomy, I’m wondering if it would be foolish to go on estrogen patches.

Does anyone else going through peri have experiences or insight into this?
