Understanding Uterine Changes During Ovulation: What to Expect

The uterus does not swell during ovulation. Ovulation is the process by which a mature egg is released from one of the ovaries. It occurs about 14 days before the start of a woman's period. During ovulation, the ovary releases the egg, which travels down the fallopian tube. If the egg is fertilized by a sperm, it will implant in the lining of the uterus and begin to grow. If the egg is not fertilized, it will be shed with the menstrual blood during the woman's period.
