The cycle typically lasts between 25 and 30 days but can be longer or shorter. A period refers to the time when a woman bleeds each month, which usually lasts between 2 and 7 days. Periods are different for every woman. Hormonal contraceptives are a common cause of vaginal bleeding between periods.
If they do cause irregular bleeding, it usually only occurs for the first 3 months of using the contraceptive. If bleeding between periods is very heavy or lasts for longer than 3 months, it may be a good idea to seek medical advice.
Changing to an alternative form of contraception can often stop breakthrough bleeding. Bleeding between periods can happen if a person does not take their hormonal contraception according to the instructions. For example, a woman may miss taking a contraceptive pill, or have a problem with a birth control patch. This can sometimes cause spotting.
Using emergency contraceptive may also cause bleeding. This applies to both forms of emergency contraceptive: the morning after pill and the IUD. Some women experience spotting shortly after becoming pregnant, marking the moment when the fertilized egg implants into the lining of the uterus.
This is called implantation bleeding. They may also feel a slight cramping in the uterus. Bleeding between menstrual periods is one early sign of a miscarriage. Miscarriages can occur at any time during pregnancy and may happen before a woman is aware that she is pregnant. Many people experience some bleeding after having a termination or abortion. Spotting may last for several weeks after having an in-clinic procedure or taking the abortion pill.
If bleeding is very heavy, seek medical advice. Some sexually transmitted infections STIs can cause vaginal bleeding. Chlamydia is a typical example. As well as spotting between periods, chlamydia can cause bleeding during or after sex. If the skin or tissue of the vagina is damaged, it can bleed.

Normal menstrual flow lasts about 5 days. It produces a total blood loss of 30 to 80 mL about 2 to 8 tablespoons , and occurs normally every 21 to 35 days. Vaginal bleeding that occurs between periods or after menopause can be caused by various problems.
Most are benign and can be easily treated. Sometimes, vaginal bleeding may be due to cancer or pre-cancer. Therefore, any unusual bleeding should be evaluated right away. Make sure that bleeding is coming from the vagina and is not from the rectum or the urine.
Inserting a tampon into the vagina will confirm the vagina, cervix, or uterus as the source of bleeding. A careful exam by your health care provider is most often the best way to find the source of the bleeding. This exam can be done even while you are bleeding. Keep track of the number of pads or tampons used over time so that the amount of bleeding can be determined. Uterine blood loss can be estimated by keeping track of how frequently a pad or tampon is soaked and how often one needs to be changed.
