Nipple swelling and pain during ovulation is a common physiological phenomenon and one of the important signs of female fertility. During the ovulation period, women's hormonal levels in the body will undergo drastic changes, causing nipple swelling and pain, as well as symptoms such as darker areola color and increased breast volume. Although these symptoms may seem ordinary, they are actually closely related to women's fertility.

In addition to ovulation, women may also experience nipple swelling and pain at other times. For example, during the first half of the menstrual cycle, women may experience nipple swelling and pain, which is caused by changes in hormonal levels in the body. In the second half of the menstrual cycle, the symptoms of nipple swelling and pain will disappear.

The symptoms of female nipple swelling and pain are not specific and will not directly affect a woman’s fertility. However, if a woman experiences symptoms of nipple swelling and pain during ovulation and lasts for more than a week, it is recommended that she seek medical attention promptly for diagnosis and treatment.

It is important for women trying to get pregnant to understand the symptoms of nipple swelling during ovulation and how to deal with them. At the same time, women also need to maintain a healthy lifestyle, such as regular diet, moderate exercise and adequate rest, to improve fertility.
