Some of the health hazards of a woman’s IUD are that it can easily lead to excessive menstrual flow, lumbosacral pain, and pregnancy with the IUD. The IUD is a relatively simple and safe contraceptive measure that causes less damage to the body. However, it is a foreign object to the body, and after implantation in the uterus, there is an adaptation process that can cause irregular vaginal bleeding. A small number of people will experience a significant increase in menstrual flow, and if there is no improvement for more than three months, you can switch to another method. At the time of menstruation, the IUD stimulates irregular contractions of the uterus, causing distension and pain in the lower abdomen, soreness at the bottom of the waist, and an increased feeling of swelling. Premature sexual intercourse after IUD can lead to gynecological inflammation, displacement of the intrauterine ring, contraceptive failure, and conception with the ring.
