After fertilization, the new potential life must make it down the tube to the uterus, where it implants. The journey from fallopian tube to uterus takes five to seven days, on average, and implantation normally occurs seven to ten days after conception. The fallopian tube is normally a fairly straight tube, but if it’s twisted or dilated because of previous infection or pelvic inflammatory disease, the embryo may wander around in the crevasses and never get to the uterus.
