Is there any other treatment for perimenopause symptom other than hormone replacement therapy?

I have been experiencing spotting for about 8 weeks now. It started after having irregular periods. I was thinking that reaching menopause would be a breeze for me. I started when I was 12 years old. I'm now over 50. I've been having a very irregular period, very light, with spotting in between periods. Last month, I was very normal. I talked to my health care professional and she said that if the progesterone treatment didn't work that I would need to start hormone replacement therapy or even birth control pills. I am very reluctant to start birth control pills and especially HRT (hormone replacement therapy) because of the serious health risks. I don't bleed heavily nor am I experiencing any pain from the bleeding. I am very aware of the health risks concerning cancer. My mother died from cervical cancer 20 years ago. My parents divorced because of my father cheating on my mother. The oncologist believed my mother had HPV complications. This is before the research confirming the link between cervical cancer and HPV. He said that she had an STD at some point and the scarring from the disease brought on my mother's cancer. My father had been having numerous affairs with other women. My mother was faithful to my dad. She had post menopause bleeding and lost dramatic amounts of weight.
This is why I don't want to risk my health to an HRT. I know the links between heart disease, strokes and other female cancers. I don't want to be tortured by the menopause symptoms either. Is there a safe alternative to HRT? Why do conventional doctors only know one therapy for menopause? They should know the serious risks to this kind of therapy but yet still adhere to it. I'm very irritated. I'm trying to do my best with everything. Has anyone had similar experiences with perimenopause? Thanks.
