  • Menstruation or having a period occurs when the lining of the uterus sheds which occurs when there is no pregnancy. A menstrual cycle occurs over the span of around 28 days and consist of the follicular, ovulatory and luteal phase.

    Follicular Phase: Day 1-14 of menstrual cycle, where day 1 is marked by menstrual bleeding. A hormone called follicular stimulating hormone as well as estrogen are produced during this phase. Increase in estrogen promotes growth of the uterine lining. As well a hormone called luteinizing hormone which stimulates ovulation.

    Ovulatory Phase: Occurs on day 14 when there is an increase of luteinizing hormone that causes release of an egg.

    Luteal Phase: Occurs during day 14-28 of cycle. There is a decrease in luteinizing and follicle stimulating hormone and an increase in both estrogen and progesterone. This stimulates significant thickening of the uterine lining.
