First off: with regard to medical matters, a great many things can happen, even though they're extremely unlikely to happen. So yes, it could theoretically happen.

The fertilized egg will attach itself to the inner lining of the uterus, the endometrium, in most cases. In some instances, it may implant itself into the Fallopian tube, which results in an ectopic pregnancy that can be fatal to the mother and fetus.
no pregnancies fail for many reasons. sometimes after eggs are fertilized they don't attach to the uterine wall, sometimes they do attach but develop an abnormality and the body aborts them, sometimes after the fertilized egg starts traveling down the fallopian tubes the fertilized egg prematurely attaches to the tubes and ectopic pregnancy develops (which leads to spontaneos abortions), sometimes they cant attach because of abnormalities in the uterine wall itself (like if a woman has endometriosis), sometimes trauma to the reproductive organs can cause damage to the embryo and that can cause the body to abort the child.
