The so-called untying is actually an operation to reopen the fallopian tubes after the bilateral tubal ligation. After the operation, you can start to prepare for pregnancy as soon as you have your period in the next month. The peak period of pregnancy is within 6 months after the tubal ligation surgery, that is, within 3-6 months. If you don’t get pregnant within this six-month period, the first consideration is that the operation has failed, and the second is that the fallopian tubes may have become blocked during the tubal unblocking process. Therefore, in this case, you may have to use other methods to prepare for pregnancy. The most common method is to use artificial insemination, which is commonly known as IVF. Therefore, after this procedure, it is important to take the time to prepare for pregnancy.
