"In a life cycle, a woman’s body is vulnerable to a variety of changes. The cycle of these changes in women every month, positively for pregnancy is called menstrual cycle. When an ovum is unfertilized, the uterus lining sheds and leads to hemorrhage, called menstruation. In a girl, menstruation starts from the age of 10 to 15 when she attains puberty and this beginning is known as menarche. The ending of menstruation is known as menopause which takes place at the age range of 50. Phases of menstrual are: Menstrual phase: Day 1, uterus lining which is prepared for implantation starts to shed which lasts 3 to 5 days. Follicular phase: A matured egg follicle releases an egg from one of the ovaries. Also, uterus starts preparation for another pregnancy. Ovulatory phase: Mid-cycle phase, this is the phase in which ovulation takes place i.e., day 13-17. End of follicular phase along with ovulation period defines the fertilization period. Luteal phase: Post ovulation phase where the fate of corpus luteum is decided. If fertilization occurs, pregnancy starts. If fertilization doesn’t occur, it marks the onset of another cycle."
