There are many methods of contraception, and the method of contraception between couples should be chosen according to the situation. If a couple is only married and has no plans to have children within a short period of time, it is recommended that they can use instrumental contraception, generally using condoms, because they are safer and more reliable and as long as they are not used they can always get pregnant and have no effect on the baby. If you have already had two or more children, you may consider using an intrauterine device or having a tubal ligation. The IUD is recommended and there are many types of IUDs available, so you can choose according to your health condition. In addition, couples who do not need to have children for a short time and have already had one or two children can also choose to use long-acting contraceptive pills for birth control.
