It is best to take the pill on an empty stomach because it facilitates the full absorption of the drug. Clinically, it should be noted that if you take the emergency contraceptive pill, you may experience withdrawal bleeding after stopping the pill, because the emergency contraceptive pill is a highly effective progestogen, and a small amount of vaginal bleeding may occur after stopping the pill. If you are taking the short-acting pill, it is recommended that you take it orally on an empty stomach and at a fixed time every day, so that it will work better and achieve the effect of contraception. In addition, if the oral contraceptive pill is a short-acting contraceptive pill and you want to plan a pregnancy, it is advisable to stop taking the pill for six months before considering pregnancy. If you are taking the emergency contraceptive pill, it is advisable to stop taking it for 3 months before considering pregnancy.
