There are many types of birth control pills, including long-acting pills, short-acting pills, and emergency pills, etc. Whether or not a patient can have intercourse after taking the pill depends on the pill chosen. If the patient chooses the emergency contraceptive pill, the pill will not work if the patient has intercourse after taking the emergency contraceptive pill. It is recommended that the patient take the emergency contraceptive pill within 72 hours after unprotected sex. In the case of mifepristone emergency contraceptive pills, they can be taken within 120 hours. If it is a compounded short-acting contraceptive pill, if taken regularly, it is best to use a contraceptive device when having intercourse within the first 1 week, and after 1 week you can have normal intercourse without contraception. If it is a long-acting contraceptive pill, you can have normal sex after 1 week of use, and it is better to use condoms before 1 week.
