When you artificially inseminate yourself you insert the semen in the cervix?

No. Not in the cervix. You have to put it inside the vagina. Your gynecologist will put it in inner and back pert of the vagina. That is called as posterior fornix. Some times the semen is processed and inserted by your gynecologist, inside the uterine cavity. You are requested not to do it yourself. You may land up in many complications. Everything has to be documented properly. You may be blamed in future of having bad character. As there will be living proof that the baby does not belong to your husband. People can and do change over the time. You can trust only two people completely. Yourself and God.
