First sign of pregnancy?

Is there any sign of a woman being pregnant that shows up before a missed period? Will a woman still experience PMS symptoms (the first few weeks of being pregnant) if she's pregnant?

This isn't a panic question - its a hopeful question.

Tender swollen breasts are another early symptom. While tender breasts are a symptom of an impending menstrual cycle, enlarged breasts are not. Sore and swollen breasts with a tingling sensation can be an early indicator of pregnancy.

e.p.t® is over 99% accurate - nothing is more accurate.

Most pregnancy tests (including e.p.t®) can be used as early as 4 days before an expected period.

However, because pregnancy hormone levels are lower the earlier you test, results are less reliable, and over 30% of pregnant women may get an incorrect result when testing that early.*

For a result that's over 99% accurate, trust e.p.t® from the day you expect your period.**

Nowadays a woman who wants to find out if she's pregnant need only make a quick trip to the local drug, grocery, or convenience store; purchase an over-the-counter home pregnancy test kit; and perform a simple test; and she'll know the results within a matter of minutes. Not so long ago, however, it wasn't nearly so quick or easy: A woman who thought she might be with child had to schedule an appointment with her doctor, make a trip to his office, give a urine sample, go home, then spend an anxious couple of days waiting for the office to telephone with the test results.

In the movies and television, a positive result was usually revealed by having a character burst into a scene and announce dramatically, "The rabbit died!" (This phrase was either shouted excitedly or whispered in a hushed tone, depending upon whether or not a positive result was the one the woman desired.) But why a rabbit? And why did it die if the woman was pregnant?
