After the tubal fluids, you can usually have intercourse after two weeks. Tubal fluids are injected into the uterine cavity through a catheter, and the pressure generated by the injection is used to determine whether there are adhesions in the fallopian tubes and the cervix, which can be used for diagnosis as well as restoring the fallopian tubes to be open. However, because the tubal fluids are operated through the vagina and cervix, it is not recommended to have intercourse too soon after the fluids are injected in order to avoid infection, and you can have intercourse after two weeks when your body recovers. If vaginal bleeding, upward infection and other uncomfortable symptoms occur after tubal ligation, it is recommended that treatment be carried out under the guidance of a professional doctor, avoiding coitus during the treatment period and taking good care of yourself as prescribed by the doctor to protect the local cleanliness and hygiene and reduce the probability of infection.
