Light bleeding when you are not having your usual period can be confusing, especially when it appears unexpectedly or your period does not follow. Bleeding without periods can happen around ovulation, after starting or changing contraception, during early pregnancy, or because of hormonal changes. Sometimes it is a temporary cycle variation, while repeated or unusual bleeding may point to an infection, a gynaecological condition or another cause that needs evaluation.

Spotting is a small amount of blood noticed on underwear or toilet paper rather than regular menstrual flow. It may be pink, red or brown and last from hours to days. A period generally has a steady flow and lasts up to 7 days.
Intermenstrual bleeding” means bleeding between periods; “breakthrough bleeding” commonly refers to unscheduled bleeding with hormonal contraception.
Light spotting can occur in early pregnancy. It should not automatically be assumed to be implantation bleeding. If pregnancy is possible, take a pregnancy test.
If you experience one-sided pelvic pain, shoulder-tip pain, dizziness or fainting with bleeding, this needs urgent assessment because ectopic pregnancy may be possible.
Ovulation can cause brief mid-cycle spotting. Anovulatory cycles, in which ovulation does not occur, can lead to irregular, delayed or unusually light bleeding.
PCOS, thyroid disorders and raised prolactin can disturb ovulation. Major weight change, excessive exercise and stress may also affect cycles. Spotting around the middle of your menstrual cycle may coincide with ovulation. An ovulation calculator can help you estimate when this phase of your cycle may occur.
Starting, stopping or missing birth-control pills can cause breakthrough bleeding. Hormonal IUDs, implants and injections can also alter bleeding patterns.
Blood thinners and some medicines may contribute. Do not stop prescribed medication without medical advice.
STIs, cervicitis, pelvic inflammatory disease and vaginal irritation can cause bleeding between periods or after sex. Fever, foul-smelling discharge or pelvic pain warrants assessment.
Fibroids, uterine or cervical polyps, endometriosis, adenomyosis and endometrial hyperplasia can cause abnormal bleeding.
Cycles can be irregular in the first few years after periods begin, after childbirth, during breastfeeding and during perimenopause. After menopause, vaginal bleeding needs medical assessment.
Persistent or recurrent bleeding can rarely be linked to cervical, endometrial or ovarian cancer, so unexplained bleeding should be checked.

If your period is late and pregnancy is possible, take a home pregnancy test. If it is negative but the period does not arrive, repeat testing may be appropriate. Spotting just before an expected period may be followed by normal flow.
Spotting followed by weeks without a period may reflect delayed ovulation, contraception, PCOS, thyroid problems, or another cause.
If spotting is followed by missed periods, repeated bleeding or new pain, seek professional medical guidance.
A menstrual period involves shedding of the uterine lining and normally causes vaginal bleeding. There is no separate condition for a normal period without bleeding.
Cramps, bloating or breast tenderness can occur even with little or no bleeding. These symptoms alone cannot confirm a period.
Seek emergency care if you are soaking through a pad every hour for more than 2 hours, especially with dizziness, shortness of breath or chest symptoms. Severe or one-sided pelvic pain, shoulder-tip pain or fainting with possible pregnancy also needs urgent assessment.
Seek prompt medical assessment if you experience:
A single episode without other symptoms can be monitored, but recurrent episodes need medical guidance.

Take a pregnancy test if there is any chance of pregnancy and make note of when the bleeding began and if it is becoming heavier. Keep track of colour, quantity, pain, recent periods, medications, and contraception.
Maintaining a period diary may assist during consultations. Use pads and liners to keep track of the quantity, and do not take hormonal medicines by yourself. A period diary can help during a consultation. Use pads or liners to monitor the amount and avoid taking hormonal medicines on your own without any prior medical guidance.
Evaluation starts with menstrual and pregnancy history, medicines, contraception and associated symptoms. A pelvic examination may be followed by a pregnancy test and selected blood tests such as a complete blood count or thyroid testing.
Depending on the pattern, your doctor may recommend:
Treatment may involve adjusting contraception, treating infection, managing PCOS or thyroid disease, or treating fibroids or polyps. Persistent or postmenopausal bleeding may need investigation first.

This can coincide with ovulation and cause brief spotting. Contraception, infection, pregnancy and uterine or cervical conditions can also cause it. Repeated episodes should be assessed.
Hormonal changes, contraception, infection, fibroids, polyps and other causes can prolong bleeding. Seek medical advice if it is heavy or recurrent.
It could occur with a shorter menstrual cycle or when spotting is mistaken for a second period. But recurring menstrual-like bleeding needs professional medical assessment.
PCOS usually causes irregular, less frequent, or absent periods. Spotting can occur, but recurring bleeding twice a month is not necessarily because of PCOS. This may require medical guidance.
