Generally, a small amount of bleeding accompanied by slight pain and soreness is normal within a week after IUI. However, if the bleeding or discomfort continues to worsen, it is more likely to be abnormal and should be treated by a doctor. However, it is a foreign object to the human body and may cause slight damage to the vaginal mucosa or endometrium, resulting in slight bleeding and discomfort. Usually oral anti-inflammatory medicine is taken and it will get better in a few days. However, if you are still bleeding after 7 days, you need to go to the gynecology department of the hospital for follow-up examination and gynecological ultrasound examination to check whether there is ring displacement or secondary infection, and follow the doctor’s prescription for medication, and also replace the birth control ring or remove the ring and take other contraceptive methods. In addition, an ultrasound should be performed 3-6 months after the IUD to see if the ring has fallen off and if the ring has shifted. Women should avoid heavy physical labor for a week after the IUD, and it is best not to have intercourse for a month to avoid loosening or falling off of the IUD. In terms of diet, you should try to eat mainly liquid and less slaggy food.
