After taking oral contraceptive pills, there will be more or less adverse reactions because each woman has a different body type. When taking oral emergency contraceptives, you can add vitamin C to reduce the side effects due to contraceptive drugs. If possible, drink a lot of boiled water two hours after taking the pill to speed up the blood circulation in the body and cause urine discharge, which will reduce the side effects of the pill. You can also eat more fruits that contain vitamin E and vitamin C, such as kiwi, bananas and apples, which can also reduce the side effects of the drug. After taking oral contraceptives, observe them first if possible, because not everyone has side effects. If there are no side effects, it is normal and you can wait patiently for your period.
