MICROANATOMY

Detailed explanation-1: -The length of the menstrual cycle varies from woman to woman, but the average is to have periods every 28 days. Regular cycles that are longer or shorter than this, from 23 to 35 days, are normal. The menstrual cycle is the time from the first day of a woman’s period to the day before her next period.

Detailed explanation-2: -Estrogen levels rise and fall twice during the menstrual cycle. Estrogen levels rise during the mid-follicular phase and then drop precipitously after ovulation. This is followed by a secondary rise in estrogen levels during the mid-luteal phase with a decrease at the end of the menstrual cycle.

Detailed explanation-3: -As hormone levels rise and fall during a girl’s menstrual cycle, it can affect the way she feels, both physically and emotionally. This is known as premenstrual syndrome (PMS) and it can make a girl feel like hiding in bed with the covers over her head. Luckily, you can do a few things to ease PMS symptoms.

Detailed explanation-4: -The estrogen level peaks approximately one day before ovulation (in a 28-day cycle, this is is typically day 13). This estrogen peak tells the brain that the egg has matured and triggers the pituitary gland to release a surge of luteinizing hormone (LH).
