Detailed explanation-1: -This causes the lining of the uterus to thicken in preparation for pregnancy. If a fertilised egg implants in the lining of the uterus, the corpus luteum continues to produce progesterone, which maintains the thickened lining of the uterus.

Detailed explanation-2: -If the egg is fertilized by a sperm as it travels down the fallopian tube, then pregnancy occurs. The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother.

Detailed explanation-3: -Ovulation is when your ovary releases a mature egg. The egg travels down the fallopian tube toward the uterus to be fertilized by sperm. The ovulation phase is the only time during your menstrual cycle when you can get pregnant.

Detailed explanation-4: -What is ovulation? Ovulation is a phase in the menstrual cycle when your ovary releases an egg (ovum). Once an egg leaves your ovary, it travels down your fallopian tube where it waits to be fertilized by sperm. On average, it happens on day 14 of a 28-day menstrual cycle.

Detailed explanation-5: -The menstrual cycle has four phases: menstrual, follicular, ovulation, and luteal. The main purpose of the menstrual cycle is to produce an egg for potential fertilization by sperm. Stress, certain medications like birth control, polyps, fibroids, and more can disrupt the cycle.
