If conception does not occur within 6 months of conception, no special treatment is required for the time being. If you have not conceived after 6-12 months of pregnancy preparation, you can undergo follow-up examinations. If you have not conceived after 12 months of pregnancy preparation, you should undergo active examinations, including gynecological ultrasound, routine white belt examination and cervical cancer screening, as well as eugenics 5 and sex hormone 6 examinations. If the above results do not reveal any problem, it is necessary to have a corresponding tubal patency test, such as tubal imaging or hysteroscopy, to find out if there are any abnormalities. If no problems are found, autoimmune antibody testing or testing for pre-thrombotic abnormalities can be performed. In short, the treatment should be tailored to the respective etiology to increase the likelihood of conception.
