Does progesterone stop your period?
Progesterone delays your period while you take it and brings one on when you stop. Your natural period starts when progesterone drops at the end of the cycle, and a course of progesterone or a progestin works the same way: the bleed usually comes 3 to 7 days after the last dose. Taken continuously, as in some HRT or with a hormonal IUD, it can make periods lighter or stop them. It isn't contraception.
Taking progesterone can stop or lighten bleeding; stopping it triggers a withdrawal bleed. What to expect on cyclical and continuous regimens.
Does progesterone stop your period? Expectation vs reality
What people often expect
“Taking progesterone will stop my periods for good”
What the evidence shows
It depends on how you take it. A course of 5 to 14 days holds off bleeding and then triggers a withdrawal bleed when you stop. Sequential HRT does the same every month on purpose. Only continuous daily use, or a hormonal IUD, tends to stop bleeding, and spotting is common for the first 3 to 6 months.
How progesterone controls your period
When does progesterone drop before a period?
After ovulation, the corpus luteum makes progesterone for the second half of the cycle. If you don't get pregnant, it breaks down, progesterone falls and the uterine lining thins and sheds as your period. The time from ovulation to your period can be anywhere from 7 days to more than 2 weeks, so the drop comes at the end of that luteal phase.

If periods have stopped and you're not pregnant, a progestogen can bring one on. Provera is given as 5 or 10 mg daily for 5 to 10 days, starting at any time, with bleeding usually 3 to 7 days after the last tablet. In a Prometrium trial, 80% of women bled within 7 days of a 10-day course.
Learn more →Can progesterone delay a period?
Yes. While you take a progestogen, it keeps the lining in place and holds off bleeding; the NHS says medroxyprogesterone can delay bleeding until after you stop the tablets. That's how it's used to control the timing of cycles. It doesn't stop a pregnancy, so if you don't bleed after stopping, take a pregnancy test.
Can progesterone stop heavy bleeding?
Progestogens are a standard treatment for heavy periods. NICE recommends considering a levonorgestrel IUD as the first treatment for many women with heavy menstrual bleeding; if it isn't suitable, cyclical oral progestogens, tranexamic acid, NSAIDs or combined hormonal contraception are options. Medroxyprogesterone can make periods lighter and shorter.

For abnormal bleeding, Provera 5 or 10 mg is taken daily for 5 to 10 days starting on day 16 or 21 of the cycle; the NHS schedule starts 16 to 21 days after your last period began, for 2 or 3 cycles. You'll usually have a period when each course ends. If you're bleeding when you start, your doctor will tell you which day to begin.
Learn more →Periods on HRT with progesterone
On sequential HRT, you take progesterone for part of each month and usually have a withdrawal bleed after each course. If there's no bleed, tell your doctor. On continuous combined HRT, with progesterone every day, you usually have no bleeding once your body adjusts, though spotting is common for the first 3 to 6 months.
Learn more →Why periods change in perimenopause
As ovulation becomes less regular, some cycles produce no progesterone. Without the monthly progesterone rise and fall, the lining can build up and shed irregularly, so periods may come more or less often and get heavier or lighter. One study found nine cycles without ovulation in the late menopause transition group.

NICE notes that progestogen-only contraception may suppress periods, which can help women with heavy bleeding. The hormonal IUD is the main example; in perimenopause, a 52 mg levonorgestrel IUD can also serve as the progestogen part of HRT. Progesterone tablets used for periods or HRT don't prevent pregnancy.

Using progesterone to manage periods and bleeding
Hormonal IUD for heavy periods
First stepNICE suggests the levonorgestrel IUD as a first treatment for heavy menstrual bleeding in many women; it can also suppress periods and provide contraception.

Strong evidenceTaken for part of each cycle to regulate or bring on bleeding, for example medroxyprogesterone for 5 to 10 days a month over 2 or 3 cycles.
Continuous combined HRT after periods stop
Strong evidenceDaily progesterone with estrogen usually means no monthly bleed once your body adjusts.

Strong evidenceTranexamic acid and NSAIDs reduce heavy bleeding if hormones aren't suitable.

See your doctor to check the uterine lining.

See a doctor; bleeding after menopause always needs checking.

Progesterone and periods: questions women ask
Does progesterone stop your period?
While you take it, it holds off bleeding; when you stop, a period usually follows within 3 to 7 days. Only continuous daily use or a hormonal IUD tends to stop periods over time.
Can progesterone stop bleeding?
It can reduce or regulate bleeding: NICE recommends the levonorgestrel IUD and cyclical oral progestogens as treatments for heavy periods. Bleeding that doesn't settle still needs investigating.
Will I get my period on progesterone?
On a course or sequential HRT, yes, usually after the course ends. On daily progesterone, bleeding usually settles to none, after some spotting in the first months.
How long after taking progesterone will I get my period?
Usually 3 to 7 days after the last Provera dose. In a Prometrium trial, 80% of women bled within 7 days of the last capsule.
When does progesterone drop in the cycle?
At the end of the luteal phase, just before your period, if you haven't become pregnant. The corpus luteum breaks down and progesterone falls, triggering bleeding.
Can medroxyprogesterone stop my period?
It delays bleeding while you take it and then brings on a lighter, shorter period when you stop. It isn't used to stop periods permanently.
Can I take medroxyprogesterone while on my period?
For missed periods, Provera can be started at any time. For abnormal bleeding, courses usually start on day 16 or 21 of your cycle. Follow the start day your doctor gives you.
Does progesterone delay your period?
Yes, while you're taking it. That's why a period follows a few days after you stop a course.
Can progesterone make periods heavier?
Irregular bleeding and spotting are common in the first 3 to 6 months of HRT and usually settle. Heavy or unexpected bleeding after 6 months should be checked. Progestogen treatments such as the hormonal IUD are used to make heavy periods lighter.
Why haven't I had a period after stopping progesterone?
A bleed usually comes within 3 to 7 days of the last dose. If it doesn't, the NHS advises talking to your doctor in case you're pregnant. Other causes, such as low estrogen from menopause or low weight, can also mean no bleed.
