Hormone Therapy Bleeding

Hormone Therapy Bleeding

“Many women who start MHT will have new vaginal
bleeding, like ‘re-starting’ your menstrual periods.
This bleeding usually stops after a couple of months”.1

Umbrella

What may the Hormone Therapy Bleeding Umbrella include?

Depending on the Source (DotS) this Umbrella may include:

  • Hormone Replacement Therapy (HRT) Side Effects
  • Hormone Therapy (HT) Side Effects
  • Menopausal Hormone Therapy (MHT) Side Effects
  • Unscheduled Bleeding

Side Effects or Not

Can hormone therapy (HT) cause side effects?

In Hormone Replacement Therapy (HRT): Side Effects of Hormone Replacement Therapy (HRT) the (United Kingdom) NHS elaborate on:

“Like any medicine, the hormones used in hormone replacement therapy (HRT) can cause side effects. But it’s common to have no side effects or only mild ones.

Any side effects usually improve over time, so it’s a good idea to carry on with your treatment for at least 3 months if possible.

Side effects of HRT can be similar to menopause symptoms, so it might not be your HRT that’s causing it.

There are different types of HRT and it can take time to find the right dose and type that works for you.

To help with side effects, a GP might suggest changing your dose, the type of HRT you take or how you take it. For example, switching from tablets to patches”.2

Who is a GP?

DotS and/or DotC (Depending on the Country) a GP may be a qualified and registered general practitioner, a medical practitioner, a medical doctor or a doctor.

Vaginal Bleeding

What is the association between new vaginal bleeding and HT?

In Menopausal Symptom Treatments: Menopausal Hormone Therapy (MHT) – Possible Side Effects of MHT the (Australian) Jean Hailes for Women’s Health explain:

“Many women who start MHT will have new vaginal bleeding, like ‘re-starting’ your menstrual periods. This bleeding usually stops after a couple of months. If you have vaginal bleeding more than 6 months after starting MHT, or vaginal bleeding that becomes heavier or goes for longer than a period, you should go back to see your doctor”.3

In Menopause Hormone Therapy: Does It Cause Vaginal Bleeding?, dated 26 November 2025, the (United States) Mayo Clinic explain:

“Menopause hormone therapy can result in light bleeding or bleeding that’s as heavy as a typical period. Often, the bleeding stops within six months. But if your bleeding concerns you, talk with your healthcare professional”.4

Management

What is the approach to managing unscheduled bleeding?

On page two in Management of Unscheduled Bleeding on HRT: What Does the Guideline Recommend?, reviewed May 2026, the British Menopause Society explain:

“Management: The approach to managing unscheduled bleeding depends on your personal risk factors and the type of HRT you are taking. Options include:

  • Offering reassurance and monitoring, if bleeding is infrequent and you have a low risk of endometrial cancer;
  • Adjusting your dose or type of HRT;
  • Performing a transvaginal (internal) ultrasound (TVS) scan to assess the endometrium (womb lining); and
  • Referring you to a gynaecologist – this does not mean that you have cancer, it just refers you to the right clinic at the right time”.5

Health Care Provider

What if I need help with my vaginal bleeding?

In Postmenopausal Bleeding: Living With – When Should I Contact My Doctor? the (United States) Cleveland Clinic note:

“Contact your healthcare provider if you experience any vaginal bleeding:

  • More than a year after your last menstrual period
  • More than a year after starting hormone replacement therapy (HRT)”.6
