Delayed menstruation with vaccination has little to do with vaccination and may be due to pregnancy, polycystic ovary syndrome, endometritis and other causes.
1. Pregnancy: How patients are in ovulation before vaccination and have sex without contraception, the probability of pregnancy is higher. During pregnancy, the endometrium of the uterus is no longer shed, so menstruation is delayed.
2. Polycystic Ovary Syndrome: The cause of the disease is still unclear, and it may be related to genetic factors, environmental factors and so on. When patients have polycystic ovary syndrome, they may have endocrine disorders, which may affect the hormone level and delayed menstruation.
3. Endometritis: it means that bacteria break through the defense of the cervix and invade the endometrium and inflammation occurs. Due to the stimulation of inflammation, the endometrium can be affected by hyperplasia, which leads to the phenomenon of delayed menstruation.
Vaccination late menstruation can also be seen in other reasons, it is recommended that patients go to the hospital in time to improve the relevant examination, follow the doctor’s instructions for treatment, to avoid delaying the condition.
