Your cycles are changing. They are shorter, or heavier, or more irregular than they used to be. You are 38 or 41 and the word perimenopause has started appearing in your thoughts. I want to help you understand what is actually happening, and what it means for your ability to conceive.
What Perimenopause Is and What It Is Not
Perimenopause is the transitional phase leading toward menopause. It is not menopause itself, and it is not the end of fertility. Ovulation still occurs during perimenopause, though it becomes less predictable. Women regularly conceive during this phase, sometimes even accidentally. The key is that as long as ovulation is happening, conception is possible.
Common signs of early perimenopause include shorter cycles, heavier or lighter periods, changes in cervical mucus, mood shifts, disturbed sleep, and occasional hot flashes. These same symptoms can also reflect thyroid dysfunction, adrenal stress, or nutritional deficiency. Before attributing everything to perimenopause, it is worth ruling out these other causes, and my free Fertility Lab Testing Panel outlines the exact markers to investigate.
If you are in your mid to late 40s and still trying to conceive, know that your body has more capacity than you have been led to believe. In Yes, You Can Get Pregnant, I lay out the exact tools I use clinically to support egg quality, hormonal balance, and cycle regularity even in the perimenopausal years. The protocol works because it addresses the underlying terrain, not just the age on your chart.
What This Means for Conception
Low AMH, which often accompanies this phase, reflects diminishing ovarian reserve but says nothing about egg quality. Women with low AMH and regular ovulation have successfully conceived naturally, including women I have worked with in their mid-to-late 40s. What matters most is protecting and supporting the quality of the eggs that are available. Research shows targeted supplementation raised AMH by 31 percent in just three months in one study. My Improving Egg Quality Masterclass walks through this protocol in detail.
How to Work With This Phase
Track your cycle carefully using a multi-hormone kit that measures both LH and progesterone. My free guide Living In Harmony supports the daily rhythm and cycle awareness practice that makes this sustainable. For the complete clinical roadmap for women navigating fertility in their late 30s and 40s, my book Yes, You Can Get Pregnant is the place to start. My team also offers one-on-one fertility coaching for women at exactly this stage.
