When do you start getting pregnancy symptoms?

Although every pregnancy is different, light bleeding, known as spotting, can be seen anywhere from six to 12 days after fertilization of the egg, according to WebMD. Many women commonly mistake this early sign of pregnancy with the start of their periods.

A milky vaginal discharge may also be observed around the same time or even earlier in some women. This is due to the thickening of the walls of the vagina. The breasts can also become tender, due to an influx of hormones during early pregnancy. Some women also report fatigue that begins about a week after conception. As WebMD points out, this tiredness is usually caused by lower blood pressure and blood sugar levels.
