Why can I still get pregnant with an IUD?

In the sexual life of men and women, many contraceptive methods have loopholes. There are always some particularly tenacious sperm and eggs that will break through layers of obstacles and combine together. Many people think that they will not get pregnant if they wear an IUD. In fact, this is not the case. If the contraceptive device in the uterus has fallen off, but the woman is not aware of it, she may get pregnant. The following is a detailed explanation of why you can still get pregnant with an IUD.

1. Improper selection of model, such as a large uterus and a small ring, which causes the ring to shift or fall off in the uterus and cannot play a contraceptive role;

2. Improper placement, such as the IUD is not placed at the bottom of the uterus, which cannot play a contraceptive role;

3. After the IUD is placed, the IUD is displaced and falls off due to squatting physical labor or sexual intercourse, resulting in contraceptive failure;

4. The woman was already pregnant before the IUD was inserted, but it was not discovered at the time;

5. If the ring is left in place for too long and not replaced in time, the endometrium will be exfoliated and washed away by menstruation month after month, causing the ring to fall off or move downward;

6. If you suffer from diabetes and have high blood sugar, the acidity of body fluids will increase, and the metal ring will be corroded, affecting contraception.

(1) The intrauterine device has fallen out, but the patient is not aware of it. This is the most common cause of contraceptive failure.

(2) The intrauterine device is placed low, close to the cervix, and cannot inhibit the implantation and development of the fertilized egg.

(3) The size of the intrauterine contraceptive device is not suitable for the size of the uterine cavity, or the device has been deformed or even broken, thus losing its contraceptive effect.

In order to avoid the above situation and reduce the chance of pregnancy with an IUD, you should go to the hospital for regular check-ups, once within 3 months after insertion, and then once a year thereafter. During the inspection, special attention should be paid to whether the IUD pops out. Once it is found to pop out, timely measures should be taken to replace it or switch to other contraceptive measures. Women who have experienced IUD fall off or become pregnant with the IUD should be inspected more frequently after the IUD is inserted again.
