Breast pain does not necessarily mean that you are about to have your period. In some cases, when a person is pregnant, the breast ducts of the breast develop early and they also experience breast pain in the breasts. Therefore, it is possible that the breast pain is due to the upcoming menstruation, but pregnancy cannot be ruled out either. Patients who have breast enlargement, breast enlargement nodules, or breast lesions may also experience chest pain. So chest pains should first be checked accordingly. If you don’t get your period when you should, you can take an early pregnancy test or go to the hospital to draw blood and check the blood HCG to know if you are pregnant. If it indicates that you are not pregnant, the chest pain is considered to be a high probability that you will have your period soon. If you have chest pain before each period, you can take medicine to relieve liver and depression to regulate, such as Prosperity Pill, Breast Ning Tablet, Breast Fetish Dissipation and other medicines to regulate. Chinese medicine believes that having liver depression and qi stagnation will result in breast swelling and pain, when you take some regulating medicine, you will get your period and also be able to provide relief to chest pain.
