Pregnancy is possible one month after the use of local anesthesia because the dose of drugs used in local anesthesia is relatively small and the drugs are quickly metabolized by the body and do not affect fetal development. Local anesthesia is suitable for minor surgery, but anti-inflammatory drugs are also used after surgery to prevent wound infection and promote wound healing. It takes some time for the body to recover after surgery, and the exact time of pregnancy needs to be judged according to the recovery of your body. If the recovery is fast, you can get pregnant in a week. If your body is slow to recover and you are still applying other medications, the pregnancy time needs to be extended to avoid other medications remaining and affecting the fetal development. It is better to drink more water after the medication to speed up the excretion of the medication. It is better not to use the medication indiscriminately during the preparation period, and you can take folic acid to prevent the developmental malformation of the fetal neural tube. After pregnancy, you should also have regular maternity checkups to see if the fetus is developing normally.
