Menstruation

Menstruation is also called menstrual bleeding, menses, catamenia or a period. The flow of menses normally serves as a sign that a woman has not become pregnant. (However, this cannot be taken as certainty, as a number of factors can cause bleeding during pregnancy; some factors are specific to early pregnancy, and some can cause heavy flow.)

Eumenorrhea denotes normal, regular menstruation that lasts for a few days (usually 3 to 5 days, but anywhere from 2 to 7 days is considered normal). The average blood loss during menstruation is 35 milliliters with 10–80 ml considered normal. (Because of this blood loss, women are more susceptible to iron deficiency than men are.)[14] An enzyme called plasmin inhibits clotting in the menstrual fluid.

Painful cramping in the abdomen, back, or upper thighs is common during the first few days of menstruation (most women experience some pain during menstruation). Severe uterine pain during menstruation is known as dysmenorrhea, and it is most common among adolescents and younger women (affecting about 67.2% of adolescent females). When menstruation begins, symptoms of premenstrual syndrome (PMS) such as breast tenderness and irritability generally decrease. Many sanitary products are marketed to women for use during their menstruation.

When does menstruation begin?

These days, girls begin to menstruate when they are about 10 to 14 years-old. The average age is approximately 12. Women will continue to menstruate until the age of 45 to 55, when menopause begins. A woman will have approximately 500 periods in her lifetime.

Can you feel ovulation?

Ovulation usually takes place roughly 14 days after the first day of the start of a period; however, the exact timing can vary greatly from woman to woman. Some women know when they are ovulating because they can feel a slight pain in their lower abdomen. Other women may bleed slightly in the middle of their cycle.

Vaginal discharge also changes at ovulation. It increases in amount and becomes more watery due to hormonal changes. This is one of the ways that women who wish to practice natural family planning (NFP) using the mucus test can find out whether it is safe to have sex or not.

Women who do not experience such symptoms during ovulation can find out when they are ovulating by taking their temperature. This will rise by 0.5 degrees Celsius when ovulation occurs. To measure temperature effectively, it must be taken at the same time every morning before getting out of bed.

Temperature readings taken from different parts of the body such as the mouth, under the arm, in the ear or in the rectum will all give a slightly different measurement. For this reason, it is important to choose one location and stick to it. When checking for temperature, rises can occur for a variety of reasons and, therefore, should not be used as the only method of detecting ovulation
