Yes. You can get pregnant during perimenopause, including in months when you skip a period entirely.
Perimenopause is a decline in fertility, not an end to it. The end comes at menopause, which is defined as twelve consecutive months without a period. Until you reach that mark, ovulation can still happen, and if ovulation happens, pregnancy is possible.
That is the short answer. The longer answer is more useful, because the thing that makes perimenopause confusing is the same thing that makes this question hard to answer for yourself: the unpredictability.
Key takeaways
- Pregnancy is possible during perimenopause, even in cycles where you skip a period.
- Menopause is the point at which twelve consecutive months have passed with no period and no spotting. Before that point you are still perimenopausal.
- Skipped and irregular periods are a sign of erratic ovulation, not of no ovulation.
- The US Office on Women's Health advises speaking to your provider about whether you still need contraception during perimenopause.
- This is general information. Whether and when to stop contraception is a decision for you and a clinician who knows your history.
Why skipped periods do not mean what people think
The assumption underneath this question is reasonable. Periods become irregular, then they start to disappear, so fertility must be disappearing with them.
What is actually happening is less tidy.
During perimenopause, oestrogen and progesterone production becomes erratic rather than simply low. Levels rise and fall in patterns that do not repeat. Some cycles you ovulate. Some cycles you do not. Some cycles you ovulate later than you ever have, which shifts the fertile window somewhere you would not think to look for it.
A skipped period tells you that one cycle was anovulatory. It tells you nothing about the next one.
This is why perimenopause is a poor guide to its own progress. A woman who has missed three periods may have ovulated in the fourth month. A woman with regular bleeding may not be ovulating at all. The bleeding pattern and the ovulation pattern come apart, and only one of them is visible to you.
If you want the fuller picture of how this transition presents, we have written a clinical guide to the early signs of perimenopause.
The twelve-month rule, and the trap in it
Menopause has a precise definition. The US Office on Women's Health puts it plainly: menopause is when periods have stopped for twelve months in a row, with no period and no spotting in that time. MedlinePlus describes it the same way, as the point from which you can no longer become pregnant.
The trap is that the clock resets.
Eleven months of nothing, then a single bleed, and you are back at month zero. That is not a technicality invented to be annoying. It is a signal that the ovaries have not finished, and a bleed after a long gap is also worth mentioning to a clinician for reasons that have nothing to do with fertility.
So the honest position during perimenopause is this: you cannot know from the outside whether any given month is one in which you can conceive, and you do not get confirmation until twelve clear months have gone by.

Perimenopause is not brief. The Office on Women's Health describes it as lasting about four years on average, and as long as ten years for some women, leading into menopause. It usually begins in the mid to late 40s, though some women notice symptoms in their mid to late 30s. MedlinePlus puts the most common age for reaching menopause between 45 and 55.
That matters here because the question is not "am I fertile today". It is "what do I do for the next several years". A decade is long enough that a decision made once, on the assumption that things were nearly over, can be wrong for most of the time it is in force.
What this means in practice
Three things follow, and none of them is complicated.
- Irregular does not mean infertile. If you do not want to become pregnant, the irregularity is a reason to be more careful, not less. The pattern that makes perimenopause hard to read is the same pattern that makes timing unreliable.
- Contraception is a conversation, not a date. There is no single age at which it becomes unnecessary for everyone. The Office on Women's Health advises talking to your provider about whether you still need it. Your history, your method, and where you are in the transition all change the answer, which is why a general article cannot give you one.
- Contraception and symptom treatment are different questions. Hormone therapy for perimenopausal symptoms is not contraception. If you are taking something for symptoms and assuming it covers both, that assumption is worth checking with the clinician who prescribed it.
It is also worth saying the obvious thing that gets lost in conversations about hormones: menopause does not protect against sexually transmitted infections, and the Office on Women's Health makes that point directly on the same page.
If you are trying to conceive
This article is written for the more common version of the question, but the reverse is a real situation and deserves an honest answer.
The same unpredictability cuts both ways. Erratic ovulation makes timing harder, and the methods people use to predict a fertile window are built on cycles that repeat. Fertility does decline through this period. We are not going to put a number on how much, because the sources we trust for this site do not publish one in a form we can stand behind, and an invented figure is worse than none.
What we can say is that this is the point to talk to a clinician rather than to the internet, and to do it sooner rather than after another year of trying.
Where treatment fits
Nothing above is an argument against treating perimenopausal symptoms. If you are awake at 3am, furious by lunchtime, and losing words mid-sentence, those are treatable, and the evidence for treating them has moved considerably. We have written about what changed when the FDA pulled its warning on hormone therapy.
The point is only that symptom treatment and contraception are separate decisions, and that the first does not answer the second.
Frequently asked questions
Can you get pregnant during perimenopause if your periods have stopped for six months?
Yes. The definition of menopause requires twelve consecutive months with no period and no spotting. At six months you are still in perimenopause, and ovulation can still occur.
Does a skipped period mean I did not ovulate that month?
A skipped period suggests that cycle was anovulatory, but it says nothing about the cycles on either side of it. Ovulation during perimenopause is intermittent rather than finished.
When can I stop using contraception?
There is no single answer that applies to everyone, and this is not a question to settle from an article. The Office on Women's Health advises asking your provider. Your age, your method and your bleeding pattern all affect it.
Is hormone therapy for symptoms the same as contraception?
No. They are different treatments for different purposes. If you are relying on something prescribed for symptoms to also prevent pregnancy, confirm that with the clinician who prescribed it.
I had one period after eleven months with none. Am I in menopause?
No. The twelve months must be consecutive, so a bleed resets the count. A bleed after a long gap is also worth raising with a clinician on its own merits.
What to do next
If you recognise yourself in the unpredictability described here, the useful next step is a structured look at your symptoms, and a conversation with someone trained in this transition rather than one who has met it in passing.
Elin is cash-pay telehealth for perimenopause in all 50 US states. The quiz is free, a board-certified clinician reviews it, and where hormone therapy is appropriate it is FDA-approved and delivered to your door, from $99/month.
