Is backup birth control needed when the Mirena (levonorgestrel-releasing intrauterine system) is placed?

It is recommended to use backup birth control for a short period after the Mirena is placed. This is because the Mirena does not provide immediate protection against pregnancy. For maximum protection, it's advised to use a backup method of contraception, such as condoms, for at least 7 days after the Mirena insertion. If the Mirena is inserted within 7 days of the start of menstruation, it is considered effective immediately, and no backup is needed. However, if it's inserted at any other time in the cycle, or if there's any uncertainty about the timing of the last menstrual period or the presence of an existing pregnancy, backup contraception should be used. Additionally, if the individual has been using other forms of hormonal contraception, the timing of stopping these in relation to Mirena placement should be carefully considered to avoid any gaps in contraceptive coverage. In all cases, it's crucial to follow up with a healthcare provider to confirm the Mirena's position and to address any questions or concerns about its use and effectiveness.
