Domestic birth control rings and imported birth control rings are roughly the same, but imported birth control rings may be a little more expensive and more varied. Whether it’s a domestic birth control ring or an imported birth control ring, they all work the same way and are used for contraception. When a woman is wearing a birth control ring again, she should take the one that suits her according to the size of her uterine cavity and the severity of her side effects and her body. If a woman has had a cesarean section, it is more appropriate to choose the IUD or T-ring with a tail wire. If a woman has had a normal birth and does not want to have more children in the future, she can also wear a contraceptive ring with a longer life span, such as the round ring or the uterus-shaped ring. Women should not choose the birth control ring blindly, but under the guidance of a doctor, it is safer to choose a birth control ring that suits you.
