menstruation

The phase of menstrual cycle in humans which lasts for 7-8 days is menstruation. It is the destruction of the mucous membrane of the uterus and consequent bleeding, which occurs periodically in humans.

Luteal phase is a stage of menstrual cycle which occurs after ovulation and before beginning of menses.

Ovulatory phase or ovulation is the midpoint of the menstrual cycle. It starts about 14 days after the follicular phase started.

the follicular phase starts on the first day of menstruation and ends with ovulation. During this phase, FSH or Follicle Stimulating Hormone and LH or Luteinizing Hormone are released from the brain and travel in the blood to the ovaries.
