What are the side effects of birth control pills?

There are two common types of birth control pills, including the short-acting pill and the emergency contraceptive pill. Both may have some side effects, including changes in menstruation, abnormal uterine bleeding, and so on.
Short-acting contraceptive pills: Short-acting contraceptive pills have fewer side effects, most of which do not cause uncomfortable symptoms, while a few patients may experience symptoms similar to early pregnancy reaction, irregular vaginal bleeding, amenorrhea, weight gain, and skin pigmentation.
Emergency contraceptive pills: Emergency contraceptive pills may cause menstrual changes, such as early or delayed menstruation, and can also lead to mild nausea and vomiting, breast tenderness, and headache. Some patients may experience abnormal uterine bleeding.
Contraceptive pills are prescription medications, and when used correctly they can treat the disease, while incorrect use can cause side effects and even delay the disease. If you need to use the drug, you should strictly follow the doctor’s instructions, and not use the drug randomly.
