• The menstrual cycle is the monthly process that occurs in women's reproductive system.
• Ovulation - Release of an egg from one ovary into the fallopian tube
• Menarche - First period

• Pregnancy - When a woman has conceived (fertilised)
• The pregnancy lasts about 9 months

• Follicular phase is the first stage of the menstrual cycle
• And during Follicular phase the ovaries development and mature eggs and one of the eggs will be release during ovulation
• Blood lost of 10 ml and 80ml is considered normal
• If there is no fertilized egg then the corpus luteum breaks down and progesterone levels decrease causing the endometrium to shed as part of the menstrual cycle
• During Luteal Phase progesterone levels increase to prepare the uterus for implantation of fertilised egg
• The luteal phase begins on day 15 and ends at the start of the next period
• Luteal phase lasts for 14 days
• The menstrual cycle can vary from woman to woman, but it usually takes around 28 days.
• Ovulation occurs around day 14
• Ovary releases an egg into fallopian tube
• Menopause occurs when ovaries stop producing eggs and periods stop permanently

• During luteal phase the egg shell station the fallopian tube during a ovulation
• The hormone causes the uterus retain it for 24 hours
• Estrogen helps to build up the lining of the uterine
• Progesterone helps maintain the lining of the uterus and prevents the release of the egg
• The first period/ stage lasts for 3 -5 days , or can range from 2 - 7 days
