Perimenopause transition
Perimenopause bleeding
Bleeding patterns often change in your 40s, but you should not be left guessing what is normal and what needs a check. This page gives a clear pathway for symptoms, checks, and treatment options.
Quick definition
Perimenopause is the transition before menopause when ovarian hormones fluctuate. Cycles may become shorter, longer, heavier, lighter, or unpredictable before periods stop completely.
Any bleeding after 12 months with no period is post-menopausal bleeding and needs a different urgent pathway.
When to seek urgent care
- Bleeding that is very heavy (for example soaking through pads hourly), with dizziness or faintness.
- Bleeding with severe pelvic pain, fever, or feeling generally unwell.
- Bleeding after 12 months with no periods (this is post-menopausal bleeding and needs prompt review).
- Unexpected bleeding plus a positive pregnancy test.
If you are unsure, contact reception or your nearest emergency centre.
Common bleeding patterns in perimenopause
Hormone fluctuations can cause cycle changes, but structural causes (such as fibroids or polyps) and endometrial problems still need to be excluded where appropriate.
Heavy or flooding periods
Often due to anovulatory cycles or common uterine causes. This can be treated and should not be ignored.
Irregular timing or skipped cycles
Cycles may shorten or lengthen in the transition, but prolonged unpredictability still needs review.
Intermenstrual or persistent spotting
Spotting between periods can be benign, but persistent bleeding usually needs imaging and sometimes endometrial sampling.
What the assessment usually includes
Step 1
Pattern and symptom review
We map bleeding timing, heaviness, quality-of-life impact, and menopause-related symptoms like hot flushes or sleep disruption.
Step 2
Targeted first tests
Depending on age and symptoms, first tests may include pregnancy testing, blood count/iron, and selected hormone or thyroid checks.
Step 3
Pelvic ultrasound
Ultrasound helps check fibroids, polyps, adenomyosis, and endometrial thickness where relevant.
Step 4
Endometrial sampling if indicated
If bleeding is persistent, risk factors are present, or scans are not reassuring, we may recommend biopsy or hysteroscopy.
Treatment options in perimenopause
Treatment is tailored to your main goal: bleeding control, symptom relief, contraception, or long-term endometrial protection.
Reduce heavy bleeding
Non-hormonal and hormonal options can significantly reduce bleeding volume and improve daily function.
Treat structural causes
If polyps, submucosal fibroids, or focal lesions are found, minimally invasive procedures may be best.
Menopause symptom support
If hot flushes, sleep disruption, or mood symptoms are significant, menopause hormone options can be reviewed safely in context.
Common questions
Frequently asked questions
Is irregular bleeding always normal in perimenopause?
No. Some change is common, but persistent, heavy, or unusual bleeding still needs assessment.
Could I still need contraception in perimenopause?
Yes. Pregnancy is still possible until menopause is confirmed, so contraception planning remains important.
Do I always need a biopsy?
Not always. Biopsy is used when symptoms persist, risk is higher, or scan findings require tissue diagnosis.
Can treatment help both bleeding and hot flushes?
Often yes, but the right plan depends on your symptoms, medical history, and whether you also need contraception.
What if my bleeding becomes very heavy suddenly?
Seek urgent care if bleeding is heavy with dizziness or weakness. Otherwise book prompt review so treatment can start early.
