Getting ready to grow a baby
During the past few days, an increase in estrogen and progesterone prompted the lining of your uterus to thicken to support a fertilized egg. At the same time, in your ovaries, eggs have “ripened” in fluid-filled sacs called follicles.
An egg is released
Once you ovulate, an egg erupts from its follicle and is swept from your ovary into a fallopian tube. (Ovulation doesn’t necessarily occur right in the middle of your cycle. For example, it could happen any time between days 9 and 21 for women with a 28-day cycle.)
