Bleeding on hormonal contraception: withdrawal bleeds, spotting and no bleeding

The bleed you get in the break from the pill, patch or ring looks like a period, but it comes about differently. Combined methods work mainly by stopping ovulation, the release of an egg, and they thin the lining of the womb (uterus). When you pause the hormones for a few days, the lining responds and you bleed. UK contraception guidance calls this a withdrawal bleed and lists it separately from menstruation. ACOG’s US patient pages simply call it your period. Both describe the same bleed.

Bleeding you plan for and bleeding you don’t

Clinicians sort bleeding on contraception into two kinds. Scheduled bleeding is the withdrawal bleed in a planned break. Anything else, from a few spots to a few days of bleeding, is unscheduled. With combined methods this is often called breakthrough bleeding. Spotting means discharge with some blood in it that may not need a pad or tampon.

The break itself is optional for many people. The NHS says a shorter pill-free break, or no break between pills (a tailored regime), may help some people with side effects. ACOG describes continuous use of the patch and some rings too. If you’d like fewer bleeds, ask your prescriber which patterns suit your product rather than changing it yourself.

What each method tends to do

Hormonal methods change bleeding in different ways. UK guidance notes that progestogen-only methods are more likely than combined ones to cause bleeding problems.

Method	What many people notice
Combined pill, patch or ring	Bleeding between periods or changes to bleeding are common in the first few months. The withdrawal bleed may get lighter.
Progestogen-only pill	Bleeding is often unpredictable. With traditional progestogen-only pills, frequent and irregular bleeding are common. It may not settle with time.
Implant	Bleeding changes are common and can carry on past the first 3 months. Bleeds often come at unpredictable intervals.
Injection	Spotting, light bleeding or no bleeding at all are common, and heavy or long bleeding can happen. No bleeding becomes common after a year or more.
IUS (hormonal coil)	For 3 to 6 months after fitting, bleeding may be longer, irregular or more frequent. Over time it often gets shorter, lighter or stops.

Some figures help set expectations. UK guidance says up to 20% of people using the combined pill have irregular bleeding in the first 3 months. With the implant, around 2 in 10 women have no bleeding at all in the longer term and 3 in 10 bleed infrequently. Fewer than 1 in 10 bleed frequently, and around 2 in 10 have prolonged bleeding, lasting 14 days or more. These figures come from studies of women.

No bleeding can be one of these patterns too, with the implant, the injection and the IUS. For the injection, US guidance says that having no bleeding doesn’t need any medical treatment, and that these bleeding changes are generally not harmful.

The first few months

The early months are when bleeding is most unsettled. ACOG describes breakthrough bleeding on combined methods as usually temporary, as the body adjusts to a change in hormone levels. UK guidance says problem bleeding in the first 3 months of a new method is common and likely to improve.

Some methods take longer. With the IUS and the implant, persistent bleeding is common in the first 6 months. With the coil, the NHS says to see a doctor or nurse if irregular or heavy bleeding continues for longer than 6 months.

None of this means you have to put up with bleeding that bothers you. US guidance says you can contact your provider at any time to talk about it.

What to rule out before calling it a side effect

Bleeding on contraception is often the method itself. Even so, UK and US guidance both ask clinicians to check for other causes first, especially if bleeding starts or changes after a method had settled. A clinician will usually ask about:

• Pregnancy. UK guidance recommends a pregnancy test for anyone sexually active with problem bleeding on hormonal contraception. The same guidance found no evidence that bleeding on a method you’ve used consistently and correctly means a higher chance of pregnancy. On the injection, US guidance suggests a clinician may check for pregnancy if a regular bleeding pattern suddenly stops.
• Infections. Chlamydia can cause bleeding, and up to 70% of women who have it have no symptoms. If you might be at risk, a chlamydia test is the minimum check in UK guidance. Risk is higher if you are under 25, have a new partner, or had more than one partner in the last year.
• How you’ve been using the method. Missed pills, illness that affects how you absorb a pill, and other medicines, including ones you buy without a prescription, can all play a part. If you’ve missed pills, you may need emergency contraception, so talk to a pharmacist, sexual health clinic or GP, or call 111 (UK), or a pharmacist or your doctor (US and elsewhere). The pill can affect how some emergency contraception works. With an IUS, if you can’t feel the threads you might not be protected against pregnancy and may need emergency contraception too.
• Cervical screening. If you’re eligible for cervical screening, a clinician will check that yours is up to date, and can offer a test if it is due or overdue.
• Other symptoms. Bleeding after sex, pain during sex, pelvic pain or unusual discharge mean a clinician will usually want to examine you. US guidance also mentions thyroid conditions, and polyps or fibroids in the womb.

If nothing else is found, the choice is yours. Some people are happy to carry on once they know the bleeding isn’t harmful. Others want to stop or switch, and both CDC and UK guidance support offering another method. A clinician can also talk about options that may help bleeding on your current method. Those depend on your method and history, so they’re a conversation to have rather than something to try at home. Don’t stop a method without a plan for contraception if you need it.

Logging bleeding while you’re on a method

On a hormonal method, the bleeding you log is shaped by the method rather than by your own cycle, so period and fertile-window estimates don’t apply. A Ruva log of bleeding days, spotting and any pain or missed pills is still useful as a diary to bring to an appointment.

When to talk to someone

Call 999 or go to A&E now (UK), or call 911 (US) or your local emergency number, if you have bleeding with a sharp, sudden and intense pain in your lower tummy, pelvic pain that’s severe or getting worse, pelvic pain with heavy bleeding, a very high temperature, or you feel dizzy or faint. These can be signs of a serious infection such as pelvic inflammatory disease.

Ask for an urgent GP appointment or contact NHS 111 today (UK), or contact your doctor or an urgent care clinic today (US and elsewhere), if you have bleeding with pain in your pelvis or lower tummy, unusual discharge, or you think you might be pregnant. If you have a hormonal coil, do the same for very heavy bleeding, lower tummy pain that painkillers don’t help, sudden lower tummy pain that gets worse or does not go away, a high temperature, or if you can’t feel the threads or they feel different.

For any hormonal method, book a routine appointment with your GP, practice nurse or sexual health clinic (UK), or your doctor or contraceptive provider (US and elsewhere), if bleeding bothers you, carries on beyond the first few months, starts or changes after it had settled, or comes after sex. The NHS suggests speaking to a pharmacist or doctor if side effects of the combined pill are still a problem after 3 months.
