If you’re entering perimenopause, you may be wondering: Do I still need birth control? And does getting an IUD at this stage of life even make sense?
The short answer is yes, you can get an IUD during perimenopause. In fact, for some women, an IUD can address more than contraception. Depending on the type of IUD, it may also help manage the heavier or more unpredictable periods that can happen during perimenopause and may even become part of your menopausal hormone therapy plan.
First, What Is Perimenopause?
Perimenopause is the transition leading up to menopause. During this time, estrogen and progesterone levels begin to fluctuate, and ovulation may become less predictable.
You might notice changes such as:
- Periods becoming shorter, longer or more irregular
- Heavier or lighter bleeding
- Hot flashes or night sweats
- Changes in sleep
- Mood changes
- Brain fog
- Vaginal dryness
- Changes in libido
Perimenopause can last for several years, and having irregular periods does not necessarily mean you can no longer become pregnant.
As long as ovulation is still occurring, pregnancy is still possible. This is why contraception can remain important during the perimenopausal years.
Why Consider an IUD During Perimenopause?
There are two main categories of IUDs: hormonal IUDs and copper IUDs.
Both can provide highly effective, long-acting and reversible contraception, but they can behave quite differently when it comes to your period.
Hormonal IUDs
Hormonal IUDs release a small amount of a progestin called levonorgestrel inside the uterus.
Depending on the device, they can provide contraception for several years. Hormonal IUDs can also make periods lighter, shorter and sometimes stop them altogether.
That can be particularly useful during perimenopause because bleeding patterns can become unpredictable or heavier during this stage of life.
A hormonal IUD may therefore be considered when you are looking for:
- Reliable contraception
- Lighter periods
- Management of heavy menstrual bleeding
- A long-term option that doesn’t require remembering a daily pill
- A possible progestogen component of menopausal hormone therapy, depending on the specific IUD
The 52 mg levonorgestrel IUD, such as Mirena, has an additional potential role during the menopause transition: it can provide endometrial protection when estrogen is prescribed as part of menopausal hormone therapy.
Copper IUDs
The copper IUD contains no hormones.
It provides highly effective contraception and can be an option for someone who wants or needs to avoid hormonal contraception.
However, copper IUDs can sometimes make periods heavier, longer or more painful, particularly after insertion.
Because heavier or more unpredictable bleeding can already occur during perimenopause, this is something worth considering when deciding between a copper and hormonal IUD.
But I’m in Perimenopause. Can I Still Get Pregnant?
Yes.
One of the confusing things about perimenopause is that your periods can become very irregular while ovulation continues to happen occasionally.
You may skip a period, or several periods, and then ovulate again.
This means that irregular periods are not a reliable form of contraception.
Menopausal hormone therapy (MHT) should also not automatically be considered contraception. If pregnancy is still possible, contraception may still be required even if you’re using hormone therapy for perimenopausal symptoms.
Can I Use an IUD With Hormone Therapy?
This is where an IUD can become particularly useful for some women.
If you have a uterus and use systemic estrogen as part of menopausal hormone therapy, you generally also need adequate progestogen to protect the lining of the uterus (the endometrium).
Without adequate progestogen, estrogen can stimulate the endometrium and increase the risk of endometrial hyperplasia and, over time, endometrial cancer.
One way to provide this protection is with progesterone or another progestogen taken separately.
Another option for some women is a 52 mg levonorgestrel IUD.
A 52 mg levonorgestrel IUD can provide endometrial protection for up to five years when used with estrogen as part of an MHT regimen, according to current clinical guidance.
Importantly, not every hormonal IUD should automatically be assumed to provide adequate endometrial protection with estrogen therapy. Lower-dose hormonal IUDs do not have the same evidence for this purpose.
Your healthcare provider can determine whether your particular IUD can be used as part of your hormone therapy plan.
How Will I Know When I’ve Reached Menopause If My IUD Stops My Period?
This is another common question.
Menopause is usually recognized after 12 consecutive months without a menstrual period, but a hormonal IUD can make periods very light or stop them altogether.
That means your bleeding pattern may no longer tell you whether you’ve reached menopause.
Your healthcare provider can look at your age, symptoms, contraception, medical history and, in selected situations, bloodwork to determine when contraception may no longer be required.
Is There an Age When You’re Too Old for an IUD?
There isn’t a single age during perimenopause when everyone suddenly becomes “too old” for an IUD.
Instead, the decision should be based on your individual health, reproductive goals, bleeding pattern, medical history and whether you may benefit from contraception or menstrual management.
For someone entering their 40s, an IUD inserted now may potentially cover a significant portion of the remaining years in which contraception is needed.
So, Is an IUD Worth Considering During Perimenopause?
For some women, absolutely.
An IUD during perimenopause may provide:
Reliable contraception, while potentially helping with, heavy or unpredictable periods and, with an appropriate 52 mg hormonal IUD, providing the progestogen component of menopausal hormone therapy.
That can make the conversation about an IUD in your 40s quite different from the conversation you may have had about birth control in your 20s.
The goal isn’t simply to prevent pregnancy. It’s to look at where you are in your reproductive life, what symptoms you’re experiencing now, and what you may need over the next several years.
If you’re experiencing changes in your periods, wondering whether you still need contraception, or considering hormone therapy, an IUD consultation can help determine whether a hormonal IUD, copper IUD or another option makes the most sense for you.
