You can get pregnant during perimenopause because fertility declines with age but does not stop as soon as this transition begins. Pregnancy remains possible before menopause, so perimenopause alone does not mean conception is no longer an option. [1] For the next step, see Can You Get Pregnant on Your Period?
Perimenopause is the transition leading up to menopause, which is a distinct stage. Menopause is reached after one full year without a menstrual cycle. [1] That distinction can help if you are trying to understand where you are in the transition, but it does not predict what will happen for you personally.
If you are thinking about pregnancy, it may help to separate two questions: whether pregnancy is possible, and what you want to do next. The answer to the first is yes, while your circumstances and goals can guide the next step. For example, you might want to talk with a clinician about your plans, whether you hope to conceive or want to avoid pregnancy. The sections below explain how changing periods relate to fertility and what conversations may help you make a decision that fits your needs.
Why can you still get pregnant when periods change?
Ovulation may continue during perimenopause, so changing periods do not make the timing of fertility easy to predict. [2] Your cycle might become irregular or skip a period, but those changes alone do not show that ovulation has stopped. [2]
Ovulation means an ovary releases an egg, and perimenopause does not necessarily bring that process to an immediate end. [1][2] You may still ovulate even as your body makes less estrogen during this transition. [2] Because ovulation can continue, pregnancy remains possible in cycles that do not follow a familiar pattern. [1][2]
For example, if your periods used to arrive at regular intervals but now vary, you cannot use the old pattern to reliably predict when ovulation might happen. Irregular periods make that timing less predictable, rather than proving that your fertility has ended. [2] A skipped period also does not, by itself, establish that ovulation has stopped. [2]
This can feel confusing because changes to your cycle are noticeable, while ovulation may not be. The practical takeaway is to avoid treating an irregular cycle as a clear sign that pregnancy is no longer possible. [1][2] If you are making decisions about pregnancy or contraception, consider your own goals and circumstances rather than relying on period timing alone.
How does fertility change during this stage?
Fertility generally declines with age, but your individual chances depend on your circumstances, and there is no single probability that applies to everyone. [1] This can make age a useful part of the picture, not a personal forecast.
For example, pregnancy rates differ across age groups: one estimate puts the chance of a naturally occurring pregnancy at about 30% per year for ages 40–44, and 10% per year for ages 45–49. [3] Those group estimates do not predict what will happen for you; your own circumstances matter.
Spontaneous pregnancy after age 50 is rare, but it can still happen during perimenopause. [3] So, reaching your 50s does not by itself mean pregnancy is impossible; consider your own goals and circumstances when making decisions about pregnancy.

What if you want to avoid pregnancy?
Changing or irregular periods do not, by themselves, rule out pregnancy, so talk with a qualified clinician if you want to avoid becoming pregnant. [2] A clinician can help you consider contraception options that fit your health, preferences, and circumstances. [2]
This conversation can be useful even if your cycles have become hard to predict. Irregular periods can make it difficult to know when ovulation is happening, and a healthcare professional can recommend contraceptive options for you during perimenopause. [2] You can bring practical questions, such as what matters most to you in a method or how it fits your daily routine.
For example, you might tell your clinician that you want to avoid pregnancy but find it difficult to track changing cycles. You can also discuss any preferences or concerns that could affect which option feels manageable for you. The best choice depends on your individual needs, so ask for guidance rather than choosing a method based only on changes in your periods. [2]
Keep the discussion focused on your circumstances; method-specific details are best covered in a dedicated birth-control guide. If you are unsure what to ask, write down your questions before the appointment and ask the clinician to explain the options in clear, practical terms.
What if you hope to become pregnant?
If you hope to become pregnant during perimenopause, conception can still happen, though fertility declines with age. [1] A clinician can help you talk through your individual circumstances and goals and decide what questions to address next.
You might start by explaining what you’re hoping for, how long you’ve been trying, and any health conditions or concerns that could affect your plans. You can also ask what information would help assess your situation and what next steps make sense for you. These details can help make the conversation specific to your needs rather than relying on broad age-based assumptions.
For example, if you’re unsure whether to keep trying on your own or seek further support, bring that question to your appointment. If your circumstances have changed, such as a new health concern or a shift in your goals, mention that too. A clinician can help you consider those factors together and discuss options that fit your preferences.
You do not need to arrive with a treatment plan or know exactly what to ask. It is enough to say that you hope to conceive and want guidance tailored to you. Keep the conversation focused on your own situation; fertility experiences differ, and general statements about age cannot tell you what will happen personally.
This discussion can also help you decide what kind of support you want going forward. You might ask which questions are best addressed now and when to check back if your plans or circumstances change. If you feel uncertain, you can say so plainly and ask the clinician to explain the choices in clear, practical terms.
What should you keep in mind?
Pregnancy remains possible during perimenopause while you continue to ovulate, so let your next step reflect whether you want to avoid pregnancy or try to conceive. [1][2]
If you want to avoid pregnancy, talk with a clinician about contraception that fits your health, preferences, and circumstances. You can bring practical questions, such as which options suit your routine or what to expect as your needs change, and ask for help weighing them. A clinician can help you choose an approach rather than leaving you to guess what is right for you. [2]
If you hope to become pregnant, discuss your goals and individual circumstances with a clinician. For example, you might explain that you are hoping to conceive and ask what next steps make sense for you. The conversation can give you a chance to get guidance tailored to your situation instead of relying on broad expectations. [1]
Either way, you do not have to make the decision alone: choose the next step that matches your goal and bring your questions to a healthcare professional.
