Perimenopause Isn’t a Pause on Possibility

Some people assume that once periods become irregular, fertility disappears. But the reality is far more complex. Perimenopause can quietly begin as early as the mid-30s, well before outward signs like irregular cycles appear. Behind the scenes, hormonal shifts—especially in estrogen and progesterone—are underway, but ovulation may still occur unpredictably.

Even when periods become erratic, ovulation doesn’t stop overnight. Fertility declines gradually, not suddenly, and conception remains possible throughout this phase. Recognizing this nuance is crucial for anyone wondering, “Am I in perimenopause?” and looking to either avoid or achieve pregnancy during this transition.

Fertility statistics back this up. According to the American College of Obstetricians and Gynecologists (ACOG), women aged 35-39 have about a 15-20% chance of conceiving each month, which decreases to 5% by age 40. Over half of pregnancies in women aged 40-44 are unintended —a clear sign that misconceptions about perimenopausal fertility are common.

Naomi Watts and Halle Berry. Two Faces of Perimenopausal Fertility

Until you’ve gone 12 consecutive months without a period, your body still has surprises for you. Woven into this unpredictability is real-life testimony that reshape how we understand fertility in perimenopause.

Naomi Watts' journey exemplifies one side of this narrative. Despite experiencing early perimenopause symptoms at a relatively young age, Watts has been candid about the fertility challenges it posed. "When I saw the doctor to find out why I wasn’t getting pregnant and was told I was nearing menopause, I coursed with shame," Watts shared.

Conversely, Halle Berry represents the other extreme. Famously pregnant at 47, Berry's story astonished many. She has candidly spoken about thinking she was "past" the possibility of conceiving. 

Together, Watts and Berry's experiences illustrate that fertility in perimenopause is a spectrum, ranging from early-onset fertility struggles to unexpected late-in-life pregnancies.

Unpredictability of Perimenopausal Pregnancy

The idea of a surprise pregnancy well into one’s 40s—sometimes called an "oops baby"—is more common than assumed. Hormonal fluctuations cause ovulation to occur unpredictably, which can easily lead to unintended pregnancies. Irregular periods may mislead women into believing they’re no longer fertile, but until menopause is confirmed (12 consecutive months without a period), ovulation—and thus the possibility of pregnancy—remains.

This unpredictability highlights the need for education. Birth control for perimenopause remains essential for those not seeking pregnancy, and awareness is key to making informed decisions during this transitional phase.

Birth Control in Perimenopause: A Strategic Tool, Not Just a Safeguard

Reliable birth control during perimenopause is about more than preventing pregnancy—it’s a tool for staying in control. Ovulation can occur sporadically without clear warning signs. Whether you’re certain you don’t want a pregnancy or still undecided, methods like IUDs, hormonal pills, or barrier methods give you the space to make deliberate, confident choices.

For many, the best birth control for perimenopause may also alleviate common symptoms like perimenopause anxiety, irregular periods, or even perimenopausal headaches. Consulting with a healthcare provider about the best contraceptive pill for perimenopause can provide both protection and symptom relief.

Navigating Perimenopausal Pregnancy: Risks, Emotions, and Empowered Choices

Perimenopause often brings emotional shifts, anxiety, and evolving priorities. Amidst this, the possibility of pregnancy can add complexity. Whether planned or unexpected, such a pregnancy may stir excitement, worry, or a mix of emotions. Acknowledging these feelings is essential, especially since symptoms like breast tenderness, fatigue, and even brain fog are common in both perimenopause and early pregnancy.

Physically, conceiving during perimenopause carries inherent risks. Health experts highlight increased chances of gestational diabetes, hypertension, preterm birth, and chromosomal abnormalities. Consulting a healthcare provider is key to assessing personal risks and making well-informed decisions.

For some women, perimenopausal pregnancy isn’t just a risk—it’s a conscious, empowering choice. Whether due to career timing, second marriages, or personal preference, late-in-life pregnancies can align perfectly with life goals.

The key lies in proactive healthcare and informed decision-making. Regular check-ups, hormone monitoring, and fertility assessments (like FSH and AMH tests) offer valuable insights. Whether safeguarding against pregnancy or planning to embrace it, having accurate information helps chart a path that feels right—emotionally, physically, and personally.
