summary

If the contraceptive ring is not suitable or displaced in the uterine cavity, it is easy to get pregnant with the ring, the probability is about 10% - 15%. Contraceptive ring as a foreign body placed in the uterus, interfere with the implantation of fertilized eggs, play a contraceptive role. However, no matter the time of releasing the IUD, it will cause more or less damage to the endometrium, which is very unfavorable for the growth and development of the fetus. Now I'd like to introduce to you what's the reason for pregnancy?.

What's the reason for pregnancy with a ring?

First: the word "contraceptive device" may be a little strange to everyone, but you must have heard of "shanghuan". We usually say the "ring" of "shanghuan" refers to the intrauterine device.

Second, they have similar principles of action, both of which achieve contraceptive effect by stimulating the endometrium and interfering with the implantation of fertilized eggs. The former inhibits the metabolism of endometrial cells by releasing copper ions. The latter inhibits endometrial growth by releasing progesterone. It interferes with the implantation of fertilized eggs.

Third: because the intrauterine device is through the endometrium, to prevent the implantation of fertilized eggs to work, so it must be placed at the bottom of the uterus, a large area of contact with the endometrium can be effective contraception. Under normal circumstances, if the contraceptive device is placed in the right position, its contraceptive success rate is very high, basically more than 99%.

matters needing attention

We can give you the following suggestions: 1. Pay attention to the position of IUD and fetus during B-ultrasound examination. If the IUD has been moved down to the lower end of the uterus which is relatively far away from the fetus, then the fetus may not be affected by the IUD and grow normally. We can even try to take out the contraceptive device at an early stage when it is feasible, which will reduce the probability of miscarriage, stillbirth and other adverse pregnancy. 2. Strict prenatal examination, close observation of fetal growth and development. 3. If there are signs of miscarriage in the first trimester, do not force abortion. Because of early pregnancy abortion, many times it is because of fetal deformity. Forced abortion often results in an unhealthy baby, which eventually leads to tragedy. Of course, it's best to avoid pregnancy with a ring. Here to remind you, after the ring, we must go to the hospital regularly. If you have a pregnancy plan, it's best to take out the contraceptive device half a year ago.
