- Ovulation. Each month inside your ovaries, a group of eggs starts to grow in small, fluid-filled sacs called follicles. Eventually, one of the eggs erupts from the follicle (ovulation).
- Hormones Rise. After the egg leaves the follicle, the follicle develops into something called the corpus luteum. The corpus luteum releases a hormone that helps thicken the lining of your uterus, getting it ready for the egg.
- The Egg Travels to the Fallopian Tube. After the egg is released, it moves into the fallopian tube. It stays there for about 24 hours, waiting for a single sperm to fertilize it.
- If the Egg Isn't Fertilized. If no sperm is around to fertilize the egg, it moves through to the uterus and disintegrates. Your hormone levels go back to normal.
