As you reach your mid-40s, your body begins going through hormonal changes. These hormone shifts are called perimenopause, the span leading up to menopause. During this time, it’s common to experience a range of symptoms, including irregular periods, hot flashes, and sleep issues, but what does it mean for your fertility? As you may know, once you’ve gone through menopause, you can no longer have a baby naturally, but can you get pregnant during perimenopause? As long as you’re still ovulating, you can get pregnant during perimenopause. While pregnancy during perimenopause isn’t as common as it is in younger women, it does happen and can result in a healthy child. In this article, we’ll discuss the connection between perimenopause and pregnancy, including how to identify perimenopausal symptoms and its impact on fertility.
After mid 40, many women start the transition to menopause, this stage is called perimenopause. This is the time when your hormones start to behave differently and fertility decreases. Whether you already have kids or want to conceive for the first time, the question is, “Can you get pregnant in perimenopause?” The answer is yes, a woman can get pregnant during perimenopause, but it’s important to understand the biological changes your body goes through and how that impacts fertility.
As we mentioned, perimenopause is the transition into menopause. It lasts around 4 to 10 years and begins around age 46. During a woman’s fertile years, the body goes through normal hormonal fluctuations throughout the menstrual cycle. Reproductive hormones like estrogen and progesterone rise and fall throughout the month, preparing the uterus for pregnancy.
As you enter perimenopause, your FSH levels tend to rise, estrogen levels start fluctuating more than before and progesterone delines. Menopause is the third stage of perimenopause and time when you don’t menstruate for 12 consecutive months, signalling the end of your reproductive years. Estrogen levels drop around 1 to 2 years before menopause, which is why it’s common to experience more pronounced symptoms.
It’s common to wonder, “Can you still get pregnant during perimenopause?” especially if you’ve started to experience symptoms related to hormonal changes. When it comes to pregnancy in perimenopause, the chances of conception decrease, as for successful conception you need a female cell, which is an egg, and male cell or sperm. Unlike sperm, which is produced continuously during reproductive years, women are born with a finite set of follicles.
Each menstrual cycle, a few follicles are recruited, and this supply diminishes with age. Around age 37-38, the number of follicles drops significantly. This affects the communication loop between your brain and ovaries. The brain sends signals to the ovaries with FSH to stimulate follicle recruitment and, in turn, receives a reply in the form of rising estrogen levels in the blood, signaling that follicles are being recruited and growing. When the ovaries provide a weak response, the brain attempts to send more FSH to achieve the same level of stimulation as before, potentially resulting in the recruitment of even more follicles and increased estrogen in blood, which can result in some disturbing symptoms, such as heavier period bleeding and breast tenderness.
However, as long as ovulation occurs, you can still get pregnant in perimenopause. The less you ovulate, the lower the chances of becoming pregnant.
You’ll likely notice your periods becoming irregular, and then you may start missing them altogether. But can you get pregnant during perimenopause without a period? While there’s still a slight chance, it’s unlikely.
Whether you’re hopeful or concerned, knowing the answer to “Can I get pregnant during perimenopause?” is important. Although it’s not as common, if you have unprotected sex during perimenopause, you could conceive. You may have heard of women with stories of “How I got pregnant during perimenopause.” While the chances of naturally conceiving during this time drop dramatically as perimenopause progresses, it’s not impossible.
Now that we’ve addressed the question, “Can a woman get pregnant during perimenopause?” it’s time to go over some common symptoms you may experience. While getting pregnant during perimenopause is possible, the farther along in this stage you are, the more pronounced your symptoms may get, and the lower your chances of conception become. If you’re trying to conceive, some perimenopause symptoms are similar to those experienced during early pregnancy, which can be confusing. Let’s look further into common symptoms that let you know you’ve entered this life transition.
As your hormones fluctuate, it can cause your periods to become irregular. You may notice they’re longer, shorter, heavier, lighter, or sporadic. During perimenopause, these changes are due to changes in estrogen levels; however, missed periods could also be a sign of pregnancy or menopause.
Your hormones impact you not only physically but emotionally, too. During perimenopause, the unpredictable nature of the fluctuations can cause a range of mood changes, including irritability, sadness, and anxiety. As these fluctuations become more pronounced, these symptoms may get more severe. You can also experience mood swings during early pregnancy, as your hormone levels rise quickly.
Fatigue is another common symptom shared with perimenopause, menopause, and early pregnancy. With perimenopause and menopause, declining progesterone levels can cause sleep issues, which may make you tired during the day. In early pregnancy, fatigue is common, and one contributing factor is the increasing levels of progesterone, which can lead to daytime sleepiness.
Hot flashes and night sweats happen when estrogen levels drop, interfering with the body’s temperature control system. Night sweats and hot flashes are the same thing, except one happens at night and the other during the day. These symptoms often worsen in menopause.
Weight gain is another common symptom of perimenopause and menopause. Although hormonal shifts get a lot of attention, remember that a more sedentary lifestyle, which often comes with aging, is a major factor in weight gain. Hot flashes with other symptoms like fatigue and mood swings, can make you less willing to participate in physical exercise, often leading to weight gain.
Regardless of whether your concern is, “Can you have a baby in perimenopause?” or “How do I know if I’m in perimenopause or menopause?” Monitoring your symptoms will give you the insights you need to better understand your body.

So, “Can I get pregnant in perimenopause?” While the answer is yes, the chances are lower. Being able to recognize the symptoms of perimenopause and understand the role hormones play in the process can empower you to make the right choices to feel your best.
Your age and menstrual cycle are the most important indicators. If you’re in your early 40s and your cycles become shorter or heavier, you’re likely in early perimenopause. If you’re in your late 40s and experience months without periods, you’re likely in late perimenopause. If you’re in your 50s and haven’t had a period in six months or more, you’re likely in menopause.
It’s important to track your menstrual cycle with a Hormone tracker like Hormona to know what perimenopause stage you’re in. Monitoring your symptoms will give you better insights into your hormonal health and cycle regularity, which you and your doctor can use to assess perimenopause progression.
If you’re wondering, “Can I still get pregnant during perimenopause?” knowing whether you ovulate or not is a top concern. Yes, you do ovulate from time to time during the early stages of perimenopause; however, as it progresses, ovulation becomes more sporadic.
The odds of getting pregnant in your 40s are very low. Although ovulation still occurs, only about 5 out of 100 women in their 40s will conceive each cycle, and this chance decreases with age. After 45, and especially as you approach 50, the odds are getting closer to zero.
Normal delay is around 4 days, as your menstrual cycle is not fixed and can vary, with normal length being between 21 and 38 days. There is no upper limit for period delay if not pregnant, as they can be late for a lot of reasons or stop altogether. If you notice your periods are irregular, it could be due to a number of reasons, including perimenopause, hormonal birth control, or reproductive conditions like PCOS. If you regularly miss periods and aren’t pregnant, you should speak to your doctor.
Perimenopause can last between 4 and 10 years, progressing steadily until your periods stop. During this time, it’s common to notice symptom progression, including hot flashes, night sweats, fatigue, mood swings, and weight changes.
While there’s no clear proof that women in their 40s have more accidental pregnancies than younger women, it’s still possible to get pregnant by surprise.
Recent US data shows about 17% of women over 40 had unintended pregnancies. That’s actually the lowest percentage compared to younger age groups. However, more women over 40 considered their pregnancy unwanted compared to others. The reason behind that could be a false belief that it’s impossible to get pregnant during perimenopause. While some use permanent birth control, many over 40 mistakenly don’t use contraception, leading to unexpected pregnancies.
Remember, as long as you’re ovulating, pregnancy is possible.
There are increased risks of getting pregnant during perimenopause since the egg quality is generally lower, and women have a higher chance of developing conditions like high blood pressure. However, it is possible to have a healthy pregnancy during perimenopause.
As women enter perimenopause, a common question is asked: can you get pregnant? Yes, as long as you’re still ovulating.
