An ectopic pregnancy cannot be put back inside the uterus. After a woman’s normal pregnancy, the embryo is deposited in the uterine cavity and gestates for ten months to give birth. Ectopic pregnancy is caused by a delay in the passage of the fertilized egg into the uterine cavity, resulting in a blockage of the fertilized egg in the fallopian tube, which causes the embryo to settle before it reaches the uterine cavity and grows outside the uterine cavity. After the embryo has been placed in the uterine cavity, it cannot be put back into the uterine cavity. After the diagnosis of ectopic pregnancy, it should be treated conservatively or surgically in a timely manner, or else it will easily cause hemorrhage, which is life-threatening. Women should do ultrasound early after pregnancy to rule out the possibility of ectopic pregnancy, once found ectopic pregnancy need to be hospitalized.
