If you take the oral contraceptive pill, you may experience irregular vaginal bleeding during the pill, mainly due to the side effects of the pill. Most of the bleeding will stop if you continue to take the pill, but in some cases, the bleeding may still occur in the vagina, which can be treated symptomatically, for example, you can take hemostatic drugs to stop the bleeding. If the bleeding does not stop even with the use of hemostatic drugs, it is recommended that after taking the pill for one menstrual cycle, other contraceptive methods should be used next month, such as the intrauterine device (IUD), which is effective and has few side effects. In addition, you can also use condoms, which are relatively safe and hygienic. In daily life, if the oral contraceptive pill has side effects, you should switch to other contraceptive methods.
