It is not possible for an ectopic pregnancy to turn into an intrauterine pregnancy, mainly because the fertilized egg can wander and find a suitable site for implantation before it settles, but once it settles, it is fixed and it is not possible to wander again. Therefore, if a patient is initially found to have an ectopic pregnancy, but later turns into an intrauterine pregnancy, two main possibilities are suggested. The first is that there is a mistake in the patient’s examination; the patient herself is pregnant intrauterine, but the time is so short that the gestational sac is not visible in the uterine cavity, or for some reason the patient has a small mass in the adnexal area, which is not a gestational sac, but is mistaken for one because it is associated with pregnancy. The second is intrauterine combined with ectopic pregnancy, which can occur if the patient has problems with her fallopian tubes and there are two fertilized eggs at the same time or if one fertilized egg splits into two after fertilization, but one goes into the uterine cavity and one goes outside the uterus.
