The following two methods of long-term contraception are the best: first, the IUD for contraception. The IUD is one of the reversible methods of contraception, and you can take the IUD out three months in advance if you plan to get pregnant and prepare for pregnancy. The IUD has fewer side effects and is acceptable to both spouses, so it is a very good method of contraception. The vast majority of birth control rings are currently valid for about 10 years, but some expire in 5 years, and can be replaced with a new ring after the expiration date. The second long-acting contraceptive method is bilateral tubal ligation, which is a clinically irreversible method. If you want to get pregnant again in the future, you can have the tubal ligation surgery, but clinically, the ligation surgery may be more effective, but it does not necessarily achieve the goal of pregnancy.
