  • The follicular phase (Day 1 to 13) – This phase begins with the menstrual phase but lasts for approximately 13 days. During this time, the pituitary gland secretes hormones which lead to maturing of ovaries. It takes 13 days for an egg to mature in the follicle. Simultaneously, follicle releases a hormone which stimulates the uterus to build up a lining of blood vessels and soft tissue.
  • Ovulation Phase (Day 14) – On day 14, the ovary releases the matured egg. The released egg then travels to the fallopian tube where it waits for fertilization.
  • Luteal phase (Day 15-28) – This is the last phase of the cycle. It occurs if the egg present in the fallopian tube is not impregnated. The egg disintegrates and by the end of this phase, the uterus lining begins to break leading to menstrual phase again.
