If the estrogen secretion in the body is high and the progesterone secretion is relatively low, it will cause the irritability after ovulation. Even if the sperm and egg are united and a fertilized egg is formed, the corresponding early pregnancy reaction will not occur after ovulation, so this situation is still caused by endocrine disorders.
