What is menstruation??

Menstruation - having periods - is part of a woman's reproductive cycle that begins when girls reach sexual maturity at the time of puberty.

During a menstrual period , a woman bleeds from her uterus (womb) through the vagina. This lasts for three to seven days. Each period begins approximately every 28 days if the woman does not become pregnant during a given Menstrual Cycle. Find out when are your wet days.

 

Why do women menstruate?

Menstruation is a rather complex process involving many different hormones, the female sex organs and the brain. The woman's internal genital organs consist of two ovaries, the fallopian tubes, the uterus (womb), and the vagina. The ovaries contain the ovules with which the woman is born, and in each period, an ovule matures due to the action of the hormones that circulate in the bloodstream.

When the ovule matures this leaves the ovary and travels through the fallopian tube down into the uterus. The lining of the uterus - the endometrium - has been thickened by the action of hormones and prepared to receive the fertilized egg. If the egg is fertilized and the woman becomes pregnant, it will stick to the endometrium. If the egg is not fertilized, the resulting hormonal changes cause the endometrium to release and menstruation begins.

The menstrual discharge is made up of the same endometrium, along with some fresh blood caused by the rupture of the very thin blood vessels inside the endometrium as it separates from the inner part of the uterus. The amount of blood that is lost due to normal menstruation is usually less than 80 ml.

 

When does menstruation begin?

Today, girls have their period or start menstruating around 10 to 14 years of age. The average age is about 12. Women will continue to menstruate until age 45 to 55, when menopause begins. A woman has about 500 periods during her life. The fertile period is when pregnancy is possible.

 

Can you tell when you are ovulating?

Ovulation usually occurs 14 days after the first day of the beginning of a period, however, the exact time can vary greatly from one woman to another. Some women know when they are ovulating because they may feel a slight pain in the lower abdomen. Other women may bleed slightly in the middle of their cycle.

The vaginal discharge also changes in ovulation. It increases in quantity and becomes more liquid due to hormonal changes. This is one of the ways in which women who wish to practice natural family planning (NFP) through the mucus test can find out whether it is safe to have sex or not.

Women who do not have these symptoms during ovulation can find out when they are ovulating when taking their temperature. This figure will increase by 0.5 degrees Celsius when ovulation occurs. To measure the effective temperature, it should be taken at the same time each morning before getting out of bed.

 Temperature readings taken from different parts of the body such as the mouth, under the arm, the ear or the rectum usually give a slightly different reading. For this reason, it is important to choose a place and stick to it. When the temperature is checked, increases can occur for several reasons and, therefore, should not be used as the sole method of detecting ovulation.

 

What influences menstruation?

As described above, menstruation is a very complex process involving many different hormones, the sexual organs and the nervous system.

First, hormones influence menstruation. If they are not in balance, the cycle will be affected in a similar way. If a woman's periods are very irregular, she can ask her doctor to measure the hormones in her blood and find out if her hormones are out of balance. This will give you a rough idea of  whether there is a serious hormonal problem. However, since what is "normal" varies a lot with respect to female hormones, blood tests are not a good measure of what can be considered imbalances.

Weight also influences hormone balance and menstruation. If a woman is low in weight, her hormones stop working properly and her periods can stop completely. Research has shown that obesity can throw hormones out of balance and make it harder for women to conceive. Stress also affects hormones. Many women find that if they are worried about something, they can influence menstruation. In some cases, the menstrual period could actually stop if she is very concerned about whether she is pregnant.

Regular exercise and staying fit and healthy can help regulate the menstrual cycle. On the other hand, getting too much exercise and overloading the body can have a negative effect on the hormones to the extent that menstruation can stop. Amenorrhea is the absence of menstruation and the main cause is still the occurrence of pregnancy, therefore it creates women's concern. Finally, overcome your worries with a little humor.
