If the IUD is placed in the correct position and can function properly, the chance of pregnancy is usually not very high; if the IUD cannot function properly due to prolonged wearing or relocation, the chance of pregnancy will be higher.
Whether or not you have a high chance of getting pregnant while wearing the IUD is closely related to whether or not the IUD is working correctly. Generally speaking, if the IUD is placed accurately in the uterine cavity and the contraceptive effect is not affected by physical activity or prolongation of time, the chance of pregnancy is usually lower.
If the IUD is worn for a long time, its contraceptive effect is weakened, or the IUD deviates from its correct position as the body moves, this situation may result in a higher chance of pregnancy, and a fertilized egg may be able to successfully implant and grow in the uterus.
In addition, no form of contraception can be 100% contraceptive, so those who wear the birth control ring, also need to do their own protection, once pregnant, should go to the hospital in time for examination.
