how do you take cyclical hrt (withdrawal bleed) as opposed to continuous (no withdrawal bleed)?

You’ll usually be recommended to take sequential (cyclical) combined HRT if you have menopause symptoms but still have periods.

It comes as tablets or patches.

There are 2 types:

monthly HRT if you’re having regular periods – you take oestrogen every day, and take progestogen alongside it for the last 10 to 14 days of your menstrual cycle every month
3-monthly HRT if you’re having irregular periods – you take oestrogen every day, and take progestogen alongside it for around 10 to 14 days every 3 months
You should have a period at the end of each progestogen cycle.

Continuous combined HRT
Continuous combined HRT is usually recommended if you’re post-menopause. This is when you have not had a period for 1 year.

Continuous combined HRT involves taking oestrogen and progestogen every day without a break.

If you’ve had a hysterectomy and take oestrogen-only HRT, you’ll take it every day.
