Uterine scarring is left as a result of cesarean section or surgery to treat diseases such as uterine fibroids. It is recommended to get pregnant about 2 years after the scar tissue has formed. Too long or too short a period of time can increase the risk of scarring the uterus. It is best to go to the hospital to have an ultrasound to measure the thickness of the uterine scar before getting pregnant again. If the thickness is around 0.6-0.8 centimeters, it is relatively safe to have another pregnancy. If the thickness is below 0.3 centimeters, pregnancy is not recommended for the time being. The scarred uterus should be tested more frequently after pregnancy, and the location of the gestational sac should be determined in the early stages of pregnancy. If it is implanted in the scar it will increase the risk of pregnancy. In the middle of pregnancy there should be increased monitoring of the placenta, there is a possibility of placenta implantation in the scar. In late pregnancy, because the elasticity of the uterine scar is relatively poor, there is a risk of uterine rupture if the fetus grows large, so it is necessary to strengthen the monitoring of pregnancy in keloid uterus.
