Among all the contraceptive pills, the short-acting compound contraceptive pill has the best contraceptive effect and causes the least harm to the body. Second, intrauterine placement of birth control rings. This contraceptive method is durable, effective and widely used in clinical practice. Third, the use of condoms for contraception is more convenient and simple, and is suitable for women who are unmarried, newly married, and have no reproductive requirements for the time being.
