3. Hoaw does it work? A menstrual cycle begins when you get your period or menstruate. This lasts for an average of 28 days. Menstrual cycle has 4 phases.

4. Phases Menstrual Phase Days 1-5 The uterus sheds its inner lining of soft tissue and blood vessels which exits the body from the vagina in the form of menstrual fluid. Blood loss of 10 ml to 80 ml is considered normal.

5. Phases Follicular Phase Days 1-13 One of these egg cells begins to mature in a sac-like-structure called follicle. It takes 13 days for the egg cell to reach maturity. Follicle secretes a hormone that stimulates the uterus to develop a lining of blood vessels and soft tissue called endometrium.

6. Phases Ovulation Phase Day 14 Ovulation is when a mature egg is released from an ovary and moves along a fallopian tube towards your uterus. Egg will stay at the fallopian tube for 12-24 hours.

7. Phases Luteal Phase Days 15-28 Main purpose is to prepare your ovary for pregnancy. If a sperm cell does not impregnate the egg cell within that time, the egg cell disintegrates.
