Generally speaking the surgery is different and when to prepare for pregnancy is also different. For example, if you have had surgery for endometrial polyps or simple residual uterine cavity surgery or IUD removal, you can go directly to pregnancy preparation 2-3 months after the surgery. However, in the case of surgery for uterine adhesions, especially in patients with serious adhesions, these patients need to use some medications to promote the growth of the endometrium after surgery, which may take 3-4 months. If it has grown better, then you can prepare for pregnancy, until then it is usually best not to prepare for pregnancy. Secondly, like hysteroscopic surgery for longitudinal uterine septum, these patients can also enter pregnancy preparation about 3 months after surgery. If the endometrium has grown well and the trauma has healed well after the longitudinal septum has been cut, these patients can enter the state of pregnancy preparation.
