3 Timeline Details to Bring When Bleeding Happens on HRT
Menopause & HormonesArticleBring the HRT start date, change dates and bleeding pattern to clinical review.

In this article
Bleeding after you thought periods were behind you can bring the spare-clothes habit back. If it happens while taking HRT, contact your clinician and bring the treatment timeline so the review starts with clear dates.
Three timeline details
-
When HRT started. Write down the start date and each product name. Bring photographs of the packaging if that is easier than remembering the preparation.
-
What changed and when. Include dose or product changes, with the dates. Note the instructions you were given and how you have been taking the medicines.
-
When bleeding began and how it behaves. Record episodes, duration and the amount you noticed. Include whether you had previously stopped bleeding. Ask the clinician how the pattern relates to the regimen you use.
Timing is a reason for assessment
The BMS guideline recommends urgent ultrasound assessment when bleeding first presents more than six months after starting HRT or more than three months after a preparation change. Heavy or prolonged bleeding warrants urgent assessment regardless of the interval. Individual risk factors can also require earlier investigation.1
These are clinical referral criteria. Tell your team about bleeding when it occurs; do not use the intervals as a reason to wait before contacting them. Ask what assessment is needed and when it will happen.
Leave with the next step in writing
Ask who will arrange investigations, how results will reach you and what changes you should make to HRT while awaiting review. Record the contact route for further bleeding.
My Body Changed. Now What? includes a symptom diary and Visit Brief. Use them to put the bleeding record, hormone details and questions together for the appointment. See the book.
