Perhaps your period is arriving earlier than expected, lasting longer than it used to, or showing up as unexpected spotting when you wipe. It can feel unsettling when you’re not sure what’s causing it.
If you're in your 40s, or even your late 30s, and noticing these kinds of changes, perimenopause could be the culprit. But the good news is that there are treatments that can help.
Key takeaways
- Irregular, heavier, or more frequent periods are common during perimenopause due to fluctuating oestrogen and progesterone levels.
- Spotting between periods or when wiping can occur during perimenopause, but should always be checked if it's new or persistent.
- Prolonged bleeding (a period that lasts over a week) should be assessed by a doctor, especially if you’re soaking through a pad or tampon every hour.
- Effective treatments can help manage heavy or disruptive perimenopausal bleeding.
What does perimenopausal bleeding look like?
Perimenopause is the years leading up to menopause (when you haven’t had a period for 12 months). And one of the main symptoms is changes to your periods.
One of the most confusing things about perimenopause is that it doesn't follow a script. Every woman's experience is different.
Fluctuating hormone levels (such as oestrogen and progesterone) make ovulation increasingly unpredictable, which in turn affects how your uterine lining builds up and sheds. This can show up as changes to your periods.
Common perimenopausal bleeding patterns include:
- Heavier flow than usual, sometimes with large clots
- Lighter or shorter periods
- Periods that arrive more frequently - sometimes every two weeks
- Longer periods that may last more than a week
- Spotting between periods or when wiping
- Cycles that vary in length from month to month
- Skipped periods followed by a heavier bleed
Are periods getting closer together in perimenopause normal?
Yes - periods getting closer together is one of the most frequently reported changes during perimenopause.
Some women find their cycle shrinks from the usual 28 days to 21 days or fewer. A period every two weeks, while disruptive, can be a normal feature of perimenopause rather than a sign that something is wrong.
That said, very frequent bleeding that is also very heavy deserves medical attention, as it can increase the risk of anaemia.
Perimenopause spotting when wiping: Is it normal?
Spotting when wiping can occur during perimenopause. When hormone levels fluctuate, your uterine lining can shed in small, irregular amounts outside of a full period, producing spotting.
But spotting isn’t always down to perimenopause. It can also result from:
- Ovulation (about 5% of women experience ovulation spotting, caused by hormonal shifts and follicle rupture when an egg is released)
- A benign condition of the cervix called ectropion
- Cervical or endometrial polyps
- Cervical irritation or infection
- Fibroids
- Thyroid disorders
- In rare cases, cervical or endometrial cancer
If you notice new spotting - especially after sex, or if it's persistent - it's worth speaking to your GP to rule out other causes.
Perimenopause heavy periods
If your periods have become significantly heavier in recent months or years, you're in good company - many women experience heavy menstrual bleeding during the perimenopausal transition.
During perimenopause, hormone fluctuations can cause your womb lining to become thicker, resulting in a heavier bleed when it does shed.
Some women describe what's sometimes called 'flooding' - a sudden, very heavy flow that can soak through a pad or tampon within minutes, sometimes with large clots.
Although flooding can be down to perimenopause, it’s best to speak to your doctor to rule out other causes and discuss appropriate treatment options.
Heavy periods can also lead to iron-deficiency anaemia over time, particularly if your periods are both heavy and frequent. If you've been feeling more tired than usual, breathless or dizzy, it's worth mentioning this alongside your period changes when you see your doctor.
When to worry about perimenopausal bleeding
Most perimenopausal bleeding changes are normal, but there are sometimes patterns that do need prompt attention. Getting things checked is about making sure you have the full picture, and that anything gets treated early.
Speak to a doctor if you experience:
- Prolonged bleeding
- Bleeding so heavy you're soaking a pad or tampon every hour for two or more consecutive hours
- Bleeding after sex
- Bleeding between periods that is new or unexplained
- Any bleeding more than 12 months after your last period (this is classed as postmenopausal bleeding and always requires investigation)
- Bleeding accompanied by pelvic pain, pressure or unusual discharge
- Symptoms of anaemia: extreme tiredness, shortness of breath, heart palpitations
How long is too long to bleed during perimenopause?
If you’ve experienced a period for over a week with no signs of stopping, make an appointment rather than wait it out. Prolonged bleeding isn’t something you should feel you just have to manage alone.
Not sure what’s normal anymore?
When you're experiencing new symptoms, it can be hard to know what’s part of menopause and what’s not. You deserve care that looks at the full picture.
Perimenopause heavy periods treatment
You don't have to just live with heavy or disruptive perimenopausal bleeding. There are effective options your doctor can explore with you.
The right approach will depend on your medical history, your other symptoms, and what matters most to you.
Hormonal treatments
- Hormone replacement therapy (HRT): HRT can help stabilise your uterine lining and reduce heavy bleeding. HRT also addresses other symptoms such as hot flushes, mood changes, and sleep disruption. If you’ve started HRT but your symptoms haven’t improved, it may need adjusting. Here are the signs your HRT isn’t working. At Voy, our clinicians can assess whether HRT is right for you and tailor a plan to your needs.
- Progestogen-only pill or injection: Can lighten periods or stop them altogether.
- The hormonal coil (e.g. Mirena): A intrauterine system (IUS) that thins the uterine lining and significantly reduces bleeding.
- Combined oral contraceptive pill: Can regulate cycles and reduce flow in perimenopausal women who are not yet at the point of needing HRT.
Non-hormonal options
- Tranexamic acid: A non-hormonal medication that reduces blood loss during a period by helping blood clot more effectively. Take it during the days of heaviest flow.
- Anti-inflammatory painkillers (e.g. ibuprofen): Can reduce both flow and period pain.
Surgical options
- Endometrial ablation: A procedure that removes your uterine lining to reduce or stop periods. It's not suitable if you want to conceive in future.
- Hysterectomy: The surgical removal of your uterus - only considered when other treatments haven't worked and bleeding is seriously affecting your quality of life.
Lifestyle changes
Lifestyle changes might help too, such as maintaining a healthy weight, reducing alcohol and managing stress. But these tweaks shouldn’t replace medical evaluation and treatment for significant bleeding.
When to see a doctor
To recap, see a GP or menopause clinician if you notice prolonged bleeding, bleeding after sex, new or unexplained bleeding after periods, and any bleeding more than 12 months after your last period. If you’re experiencing any symptoms of anaemia (extreme tiredness, shortness of breath or heart palpitations), these should always be evaluated too.
