Aunt refers to menstruation. The third vaccine in this case may refer to the cervical cancer vaccine or the New Crown vaccine. Although you can get the third vaccine with menstruation, it is best to avoid the injection during menstruation. Avoiding the discomfort of menstruation in women is not distinguishable from adverse reactions after vaccination. Usually the common adverse reactions after vaccination are usually local pain, itching, hard nodules, etc. Individuals may have systemic discomfort symptoms, such as fever, headache, dizziness, fatigue, nausea, vomiting, abdominal pain and other symptoms, such as the new crown vaccine, HPV vaccine, etc., after vaccination, the adverse reactions are relatively mild and do not require special treatment. Premenstrual symptoms may also include headache, dizziness, fatigue, nausea, vomiting, abdominal pain, etc., which vary in severity. It is difficult to distinguish adverse reactions after vaccination from PMS, so it is necessary to avoid injections during menstruation. After vaccination, if you have any uncomfortable symptoms, you need to go to the hospital as soon as possible, by the doctor according to the specific situation, to formulate individualized diagnosis and treatment plan, so as not to delay the condition.
