There is no one type of free ring or self-pay ring that is better, as long as it is adapted, whether it is free or self-pay is good. There are many types of contraceptive rings, each with its own advantages and disadvantages. Clinically more commonly used T-copper ring, round ring, uterus-shaped ring, round uterus copper, etc.. The doctor will need to choose the appropriate type of IUD to place according to the size of the uterine cavity, the degree of cervical laxity, and whether there is a history of IUD failure. There is no difference in the quality of the IUDs, so no matter whether it is free or self-funded, as long as it suits you, it is a good IUD. Don’t have sex for half a month after the IUD is placed, and go to the hospital three months later for a recheck to see if the IUD has been lost or shifted. If you have any discomfort after the IUD, please consult the hospital in time to avoid adverse consequences.
