Your breasts are now twice their normal size.

One of the early trademarks of pregnancy are sensitive, sore breasts. This is caused by an increase in the level of hormones. However, this too will pass. Once your rising hormone levels have stabilized and your body adjusts, the tenderness will diminish. You should be feeling much better after the first trimester.

The monthly visitor has failed to visit.

This actually isn't one of the best signals that you may be pregnant. You may have some spotting due to implantation bleeding (although this is uncommon). Most women notice other symptoms before this one comes along. A pregnancy test is usually your best bet.

You suddenly crave apples and pretzels (or any other unusual food for that matter).

Many women claim to crave certain foods during pregnancy. Food aversions are also very common. You may want to take a pregnancy test if your favorite food no longer lingers for your attention.

Your mornings are often spent over the toilet bowl (morning sickness strikes again).

Most women don't experience morning sickness until about a month after conception. These peak around 8 to 10 weeks into your pregnancy and then level off in the second trimester. A lucky few escape it completely.

Exhaustion sets in after a normal day at work

The increased hormone levels and changes in your body can make you exhausted. Your energy should increase in the second trimester.

Aromas that are 15 feet away now seem to be invading your space.

Many newly pregnant women experience increased sensitivity to odors. This may be a side effect of increasing levels of estrogen in your body.

You sprint to the bathroom every five minutes.

#1 proof! Home pregnancy test declares that "Yes, you are pregnant." Despite any previous threats.

In spite of all of this, often when women are asked to name what the most empowering moment of their lives was, the most common answer is giving birth.
