The term “aunt” generally refers to a woman’s menstrual period. The second dose of the vaccine does not usually cause a delay in menstruation.
The vaccine is used to prevent human papillomavirus (HPV) infection and does not affect ovarian function after the injection, so it will not cause delayed menstruation. If menstruation is delayed after vaccination, it should be considered whether it is caused by pregnancy or endocrine disorders.
For women who are sexually active, blood should first be drawn for human chorionic gonadotropin to rule out the possibility of pregnancy after menstrual delay. If there is no pregnancy, it may be related to recent mental tension, excessive pressure, environmental changes, etc. Some women may experience delayed menstruation due to excessive psychological fluctuations after receiving the vaccine, which is not a cause for concern and will improve on its own.
Therefore, if menstruation is delayed after vaccination, you can continue to observe. If menstruation is still delayed, you should go to the hospital to have a relevant examination, and under the guidance of a professional doctor to clarify the cause of the disease and target treatment.
