This is an automatically translated article.

Menstruation that lasts only 1-2 days can be an early sign of pregnancy. However, it can also be caused by other factors such as lifestyle, birth control, and health conditions. So is it normal for a period to last 1 day or 2 days?

1. What is called a normal menstrual cycle?

The normal menstrual cycle is about 28 days, ranging from 21 days to 35 days. The number of menstrual days from 3 to 5 days, ranging from 2 to 7 days is also considered normal.

2. Is it normal to have little and short menstrual periods?

If your period is usually long, then suddenly it is 1-2 days short, it can be due to many reasons, it can be:
2.1. Pregnancy Pregnancy can be the reason for a short menstrual cycle, where menstruation lasts 2 days or less.
When a fertilized egg attaches to the lining of the uterus, implantation can cause short-term bleeding with a color ranging from light pink to dark brown.
Implantation bleeding usually occurs 10-14 days after conception. But not all pregnant women experience this phenomenon. It only occurs in about 15 to 25% of pregnancies.
2.2. Miscarriage Miscarriage can be mistaken for a period, so many women with short, light periods don't know they're pregnant. The bleeding may be spotty or heavy, depending on the length of the pregnancy.
Other symptoms of miscarriage include:
Cramping Abdominal or pelvic pain Back pain

2.3. Breastfeeding Breastfeeding can change your hormones and the nature of your menstrual cycle. In which, the menstrual period is less than usual and only 1-2 days left.
2.4. Contraceptives Birth control pills or hormone therapy as well as an intrauterine device (IUD) can make periods shorter.
The hormones in birth control pills can thin the lining of the uterus, thereby shortening the menstrual period. Bleeding between periods can occur in women taking progestin-only pills.
Other drugs that can affect menstrual cycle length include:
Anticoagulants Antipsychotic drugs Antidepressants Steroids Herbs, such as ginseng Tamoxifen (A medicine used to treatment of certain types of breast cancer) 2.5. Ectopic pregnancy One of the first signs to diagnose an ectopic pregnancy is vaginal bleeding accompanied by pelvic pain. Fallopian tube rupture can occur as a fertilized egg continues to develop in it. This is an obstetric emergency because it can cause massive bleeding in the abdomen.
Go to the hospital immediately if you experience symptoms of an ectopic pregnancy, such as:
Cramping abdominal or pelvic pain, usually on one side Fainting or dizziness Unusual vaginal bleeding Increased pressure force on the rectum 2.6. Stress Prolonged stress can affect hormone levels, which in turn affects the menstrual cycle.
Severe stress can cause irregular periods, shorter periods than usual, or no periods at all. Most periods will return to normal once the stress is over.
2.7. Strong weight loss Weight loss can cause irregular periods. Eating disorders such as anorexia nervosa and bulimia nervosa can cause periods to stop altogether.

2.8. Exercising too much
Exercising too hard can cause irregular periods or temporary cessation of periods.
Excessive physical activity can cause the body to not supply enough energy to the hypothalamus, thereby slowing or stopping the release of hormones that control ovulation.
2.9. Thyroid disease Thyroid disease causes an over- or under-secretion of thyroid hormone. This is a hormone that plays an important role in the menstrual cycle. When production isn't enough, it can cause periods to be less frequent, shorter, or irregular.
Symptoms of thyroid disease can vary, depending on the type of disorder, the most common of which include:
Weight loss or gain Difficulty sleeping or feeling very tired Increased or decreased heart rate Syndromes polycystic ovary (PCOS) 2.10. Pelvic inflammatory disease (PID) Pelvic inflammatory disease (PID) is a sexually transmitted infection that occurs when bacteria enter the vagina and spread to the uterus and upper genital tract.
PID can cause irregular, but heavier, longer or more painful periods.

2.11. Other factors Less common conditions that can cause irregular periods or shorter-than-normal periods include:
Cervical stenosis Premature ovarian failure (POF) Asherman syndrome Anemia Anemia Glandular disorders Yen Uterine cancer Cervical cancer 2.12. Age Newly menstruated or menopausal women may have irregular periods for several years before they stabilize or stop completely.
