In general, the human papillomavirus, or HPV, vaccine does not usually delay menstruation. Delayed menstruation after vaccination may be caused by self-factors, pregnancy, endocrine disorders and so on.
1. Self-factors: Due to the different physique, the body’s tolerance to HPV vaccine is different. After taking the medication, if you are affected by factors such as high pressure at work, change of environment, staying up late, etc., it may affect your menstrual cycle.
2. Pregnancy: If you have a normal sex life and do not take contraceptive measures during sex, there may be a combination of sperm and egg to form a fertilized egg, leading to pregnancy. After pregnancy, hormone levels in the body will rise, triggering the phenomenon of menopause and delayed menstruation.
3. Endocrine disorders: Endocrine disorders may cause changes in hormone levels and delayed menstruation after HPV vaccination.
If there is a delay in menstruation, it is recommended to go to a regular hospital, under the guidance of the doctor for examination, to identify the cause of the disease, and then take targeted treatment.
