As a norm here on Facts Legend, we are going to cover ‘what’, ‘how’ and ‘why’ in our list of menstruation facts. It is vital that you get a thorough knowledge on the topic but in an easy to grasp fashion.
So, here is our period facts for beginners…
1. Menstruation is the monthly discharge of blood and the lining of uterus (called endometrium).
2. Menstruation starts from the age of 12 to 15 years. The first menstrual cycle is called menarche. In some cases, girls start menstruating from the age of 8 or 9 years and it is considered normal.
3. Menstruation continues till the last menstrual cycle which is called menopause. Menopause takes place when women reach around 45 to 55 years of age. There are other reasons for improper timing (delay or preponement) or stopping of the periods.
4. Length of time from one cycle to another cycle of menstruation is 21 to 45 days in young women and 21 to 31 days in adults.
5. In a menstrual period, the bleeding happens for 2 to 7 days.

How Menstruation Takes Place? (Facts 7-25)
In the previous segment we covered the ‘What’. This segment of our menstruation facts article will cover the ‘How.’ Read on…
7. It is important to understand that menstruation is not a single phenomenon. It is coupled with multiple phenomena and what women experience is menstruation and menstruation cycle.
8. This is the reason why women undergo a lot of changes in their moods, emotions and behavior during their periods.
9. From Day 1 to 5, follicles of ovary start developing. Each ovary contains 40,000 follicles. Each follicle has an egg. Day 1 is also the first day of menstrual bleeding.
10. From Day 5 to 8, only one follicle develops, other follicles shrink back into the ovary. Estrogen levels starts increasing and the follicle keeps on growing. By Day 8, bleeding usually stops.
11. The lining of uterus thickens because of high estrogen levels in blood. This lining of the uterus is rich in nutrients and blood so that it can nourish the embryo if pregnancy happens.
12. Because of high estrogen levels, endorphins are released which are feel-good chemicals of brain. These endorphins are also released during physical activity. Because of these endorphins, women feel relaxed and calm during these days.
13. Just few days before Day 14, estrogen levels peak and luteinizing hormone (LH) also increases.
14. Because of the increasing levels of LH, mature follicle bursts and releases egg from the ovary. The process of bursting the follicle and releasing the egg is called ovulation.
15. Ovulation takes place on Day 14. If a woman engages in sex on Day 14 or three days earlier to Day 14, it is most likely that the woman would get pregnant.
16. Did you know that sperms can live for 3 to 5 days in woman’s reproductive organs and a woman’s eggs can live for around 12 to 24 hours.
17. Few days before Day 14, levels of estrogen are at its peak and hence women feel happy physically and emotionally.
18. From Day 15 to Day 24, the egg travels from ovary towards the uterus via fallopian tubes.
19. The follicle which is ruptured starts releasing progesterone. Just like estrogen, progesterone helps in thickening the lining of the uterus.
20. The woman would get pregnant if the sperm joins the egg in the fallopian tube. This process of joining of sperm and egg is called fertilization.
21. If the process of fertilization takes place, the fertilized egg will travel towards the uterus and implant itself into the walls of the uterus.
22. If the egg is not fertilized, then the egg breaks apart. On Day 24, estrogen and progesterone levels drop.
23. Few women feel irritable, depressed or angry during the premenstrual week i.e. from Day 15 to Day 24.
24. Finally, the unfertilized egg leaves the body with the lining of the uterus which marks the Day 1 of another menstruation period.
25. It is important to remember that on Day 1 the follicles start growing for the next periods or pregnancy.
This sums the whole menstrual cycle in short.
