Going back on the pill in my 40's. Suppose to help with physical/mental issues of perimopause symptoms?

Turned 45, and besides some digestive issue that I hear can happen with perimenopause.. also some hot flashes, odd stomach aches/pains.. and extreme mental issues, (feel of gloom and doom).. My gyno , who I had for the first time, .. said to go back on the pill. I was on them for 20 years and went off 3 years ago, thinkingn it was the right thing to do , give the body a rest..etc.. Anyway, now I don't know what to do.. Should I go back on them? She says suppose to help with balancing out hormones for the better. She gave me a low dosage - April 21.. (name).. Kind of hate to be back on them though, and wish I knew of a alternative to help my mental/physical state these months. Has anyone out there gone back on the pill to help with pre-menopausal symptoms?Thanks
