Answer:
1. The luteal phase begins after ovulation. It lasts about 14 days (unless fertilization occurs) and ends just before a menstrual period. In this phase, the ruptured follicle closes after releasing the egg and forms a structure called a corpus luteum, which produces increasing quantities of progesterone.
2. Ovulation happens about 14 days before your period starts. If your average menstrual cycle is 28 days, you ovulate around day 14, and your most fertile days are days 12, 13 and 14
3. A group of symptoms that occur in women, typically between ovulation and a period.
The cause isn't fully understood but likely involves changes in hormones during the menstrual cycle.
Symptoms include mood swings, tender breasts, food cravings, fatigue, irritability and depression.
Lifestyle changes and medication may reduce symptoms
4. The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone
5. Progesterone helps to regulate your cycle. But its main job is to get your uterus ready for pregnancy. After you ovulate each month, progesterone helps thicken the lining of the uterus to prepare for a fertilized egg. If there is no fertilized egg, progesterone levels drop and menstruation begins.
6. At menopause, you stop producing oestrogen (the main sex hormone in women) and this can lead to menopausal symptoms. Oestrogen levels can vary in the time leading up to the final menstrual period (called the perimenopause).
