"Perimenopause, in a nutshell, is highly complex. And if you're in perimenopause, I really suggest you see a menopause specialist that you can meet with, tell health, talk to. A human, please don't go to an online algorithmic answer. Perimenopause is complicated. Your cycles can change with HRT. Your mood symptoms can change. You may still cycle and still be in perimenopause. Perimenopause can start in your 30s. And it's something that, if done well, treated well, will certainly ease the transition into menopause for a lot of women and make them so much more productive during this really difficult window for a lot of us."
