Missed Period
The day that you expect your period is the official day that you can take a home pregnancy test. These tests are pretty good and rarely give false results although blood tests are the most accurate.

Morning Sickness
Only about 50% of women will experience morning sickness and it can be everything from merely a queasy feeling or actual vomiting.

Breast Soreness
Breast tenderness is experienced by many women, both during pregnancy and prior to their periods.

Headaches
Headaches may be a pregnancy symptom, but it is not necessarily a pregnancy sign.

Bloating
Again, this is a symptom of pregnancy, but not necessarily a sign.

Vaginal Discharge
Vaginal discharge, without itching or burning, may be a sign of pregnancy.
