The amount of time that taking birth control pills can cause bloating is uncertain, and there are some individual differences that vary from patient to patient. Bloating from birth control pills is one of the more common side effects of the drug in women. In addition, it may also cause nausea, vomiting and early pregnancy reactions such as dizziness. Particularly with long-acting contraceptives, the side effects can be more frequent, causing an increase in leukorrhea, which is mostly colorless, clear and watery, and is more noticeable after the onset of menstruation. In addition, it can cause prolonged periods, cause abnormal menstrual flow and even amenorrhea. However, these side effects are generally temporary and can return to normal after stopping the medication and do not require special treatment. In addition, there are certain contraindications to the use of contraceptive pills, and it is recommended that women need to get the guidance of a specialist.
