Other Symptoms Typical of Pregnancy

The fertilization of the egg by the sperm does not cause any symptoms in the woman. However, when embryonic implantation occurs, the woman may or may not observe slight, occasional spotting. This is implantation bleeding, but it does not always appear, and this does not mean that the woman has not become pregnant.

Along with implantation bleeding, other symptoms typical of pregnancy include fatigue, a missed period, the onset of nausea, cravings, etc.
