Spotting between periods in perimenopause
Perimenopause bleeding between periods, from light spotting when you wipe to brown discharge, is common as hormones swing and ovulation becomes irregular. It's also common in the first months of HRT. Bleeding between periods or after sex should still be checked by a doctor, because polyps, infection and, rarely, precancerous changes can cause it too. Any bleeding after 12 months without a period always needs checking.
Spotting and brown discharge are common as hormones swing, but bleeding after sex or heavy bleeding between periods needs a check. What's normal and what isn't.
Perimenopause spotting: expectation vs reality
What people often expect
“Spotting in your 40s is just hormones and doesn't need checking”
What the evidence shows
Perimenopausal bleeding has many causes, from unstable ovarian function to polyps and, rarely, premalignant changes. Guidance is to rule out cervical causes, infection and pregnancy first, then use a transvaginal ultrasound as the first scan. Saline or gel contrast ultrasound improves accuracy when the lining needs a closer look. Hormones are the most likely answer, but only after the rest is ruled out.
Why perimenopause causes spotting between periods
No ovulation means an unstable uterine lining
When a cycle skips ovulation, there's little progesterone to hold the uterine lining steady, so it can shed in bits between periods. Estrogen can run high and erratic in perimenopause while progesterone falls, which feeds that unstable pattern. The result is spotting before a period, after it, mid-cycle, or instead of it. It often comes and goes as some cycles ovulate and others don't.
Why perimenopause spotting is often brown
Brown spotting or brown discharge is usually old blood. When the lining sheds slowly and in small amounts, the blood takes longer to leave the body and darkens on the way. It's common with the unstable lining of perimenopause, and at the start or end of a period. Brown color alone isn't a warning sign, but the pattern matters: spotting between periods or after sex should still be checked.
Polyps and fibroids cause spotting between periods
Benign growths such as endometrial polyps and fibroids become more common with age and often cause spotting between periods or after sex. A speculum examination should exclude causes in the cervix and vagina, and infection or pregnancy should be ruled out, before assuming hormones alone are to blame. Polyps can usually be removed with a quick hysteroscopic procedure. Getting it checked usually brings quick reassurance and a simple fix.
Spotting on HRT: breakthrough bleeding
HRT and progestogens can cause spotting while your body adjusts. Irregular bleeding or spotting is common in the first months, and on continuous combined HRT it's common for the first 4 to 6 months. It usually settles within 6 months. Tell your doctor at your 3-month review, and see them if bleeding lasts more than 6 months, gets heavier, or starts after a spell without bleeding.
Spotting around ovulation
Some women have a little bleeding or discharge around ovulation, about 14 days before a period, often with a one-sided ache. This can become more noticeable in perimenopause as hormone swings get bigger. It's usually harmless if it's light, short and mid-cycle, but the NHS still lists bleeding between periods as a reason to see a doctor, so mention it if it keeps happening.
Spotting after menopause is different
Once you've gone 12 months without a period, any bleeding, even a small amount or a single episode, needs checking. It's not usually serious: the most common causes are thinning of the vaginal or uterine lining, polyps, and a thickened lining. But it can be a sign of cancer, so a doctor should refer you to a specialist, and you shouldn't wait more than 2 weeks.
How common is spotting in perimenopause?
4–6 months
2 weeks
Abnormal bleeding is described as frequent in perimenopause, but there's no reliable single figure for spotting alone.
Causes of spotting to rule out
Spotting in perimenopause is often hormonal, but it's also the symptom most likely to hide something treatable. These are the causes a doctor checks first.
Polyps
Spotting between periods or after sex, sometimes with heavier periods.
Test: Transvaginal ultrasound, hysteroscopy
Infection
Check →Spotting with unusual discharge, a smell, pain when peeing or pelvic pain.
Test: Sexual health clinic or doctor
Pregnancy
Check →Spotting around when a period was due, with a late or light period, sore breasts or nausea.
Test: Pregnancy test
HRT or hormonal contraception
Check →Started in the first months of a new treatment or after a dose change.
Test: Talk to your prescriber after 3 months
Cervical changes
Bleeding after sex. Check your Pap test is up to date.
Test: Speculum examination
Vaginal dryness
Check →Light spotting after sex or when wiping, with dryness, soreness or itching.
Test: Doctor's examination
What helps spotting between periods
Keep a bleeding diary
First stepNote the dates, amount and color of any spotting, and whether it followed sex, exercise or a new medicine. Add your period days. Bring the diary to your appointment: it's the first thing a doctor will ask about when sorting causes, and it shows whether spotting follows a cycle pattern or is random.

If this is the causeSpotting often settles within 3 to 6 months on a new regimen. If it continues, gets heavier, or starts after a spell of no bleeding, the dose of progestogen, the type of HRT or how you take it can be changed. Don't just stop HRT without talking to your prescriber.
Related guide →Hormonal treatment for irregular spotting
Strong evidenceOnce other causes are ruled out, oral progestogens, the combined pill or a levonorgestrel IUD can steady bleeding from cycles without ovulation when it's interfering with daily life. In less severe cases and for bleeding between periods, watching and waiting is also reasonable once serious causes are excluded.
Related guide →Remove polyps causing spotting
If this is the causeIf an ultrasound shows a polyp or a fibroid inside the uterine cavity, a hysteroscopic procedure can remove it, usually as an outpatient. This often stops spotting completely and provides tissue to confirm it's benign. If the scan is normal and the spotting is hormonal, the options above for steadying the lining are the next step.
Treat vaginal dryness behind spotting after sex
If this is the causeIf spotting comes from thin, dry vaginal tissue, lubricant for sex and a vaginal moisturizer help, and low-dose vaginal estrogen treats the tissue itself. Bleeding after sex still needs checking first to rule out cervical causes. Many women find that once the tissue is healthier, both the dryness and the spotting after sex stop.

When spotting and bleeding need a doctor
Urgent: Any bleeding 12 or more months after your last period
Always needs checking, even if it's small or happened once. You should see a specialist within 2 weeks.
Bleeding between periods or after sex
See a doctor. Polyps, infection, cervical changes and, rarely, precancerous changes need ruling out.
Spotting that continues after 3 months of HRT, or gets heavier
See your prescriber. Bleeding lasting more than 6 months after starting HRT needs checking.
Spotting with pelvic pain, fever or unusual discharge
See a doctor or sexual health clinic. This can be an infection.
Spotting in perimenopause: questions women ask
Is brown spotting normal in perimenopause?
Often, yes: it's usually old blood from an unstable lining that sheds slowly. But spotting between periods or after sex should still be checked, whatever the color, to rule out polyps, infection and cervical changes.
Is spotting between periods normal in perimenopause?
It's common, because cycles without ovulation leave the lining unstable. But it's not something to ignore: the NHS advises seeing a doctor for bleeding between periods. Usually the cause is hormonal or a benign polyp, and both are treatable.
Why am I spotting on HRT?
Spotting is a common side effect in the first few months while your body adjusts. On continuous combined HRT it's common for the first 4 to 6 months. It usually settles; if it lasts beyond 6 months or gets heavier, see your prescriber about changing the dose or type.
What tests will a doctor do for spotting?
An examination with a speculum, tests for infection and pregnancy if relevant, and usually a transvaginal ultrasound. If the lining needs a closer look, a contrast ultrasound, biopsy or hysteroscopy may follow. Most of these are quick outpatient tests, and most results are benign.
Is spotting instead of a period normal in perimenopause?
It can happen when a cycle doesn't ovulate and the lining sheds unevenly. Take a pregnancy test if a period is late, and see a doctor if spotting between periods keeps happening. Tracking your cycles and spotting in a diary makes the pattern clearer for you and your doctor.
Why do I spot when I wipe in perimenopause?
Light spotting on the tissue can come from an unstable uterine lining, the start or end of a period, or thin, dry vaginal tissue. If it keeps happening between periods or after sex, see a doctor to rule out polyps, infection or cervical changes.
Is spotting a sign of menopause?
Spotting is a common sign of perimenopause, the years before your last period, as cycles become irregular. After menopause, when you've gone 12 months without a period, spotting is never expected and always needs checking.
What is breakthrough bleeding on HRT?
Unexpected spotting or bleeding while on HRT. It's common in the first few months and usually settles within 6 months. If it lasts longer, gets heavier or starts after a spell without bleeding, see your prescriber.
Can stress cause spotting in perimenopause?
Stress and anxiety are among the everyday causes of irregular periods that the NHS lists, along with big weight changes and heavy exercise, and they can add to an already unstable cycle. But stress should be the last explanation, not the first: bleeding between periods or after sex still needs a doctor to rule out polyps, infection and cervical causes.
