The intrauterine insertion of the IUD takes only 5-10 minutes to perform. After the IUD is placed, it is important to take more rest. There will be vaginal bleeding for a few days, so it is necessary to pay attention to vulva hygiene, wear good air-permeable cotton underwear and avoid eating raw, cold and spicy food to avoid pain in the abdomen or the manifestation of fire. Avoid sexual intercourse for a short period of time to avoid inflammatory infections. After a normal period, see your doctor for an examination to see if the IUD has shifted or fallen off. If everything is normal, you can have sex after your period is completely over and you will have a better contraceptive effect.
