1. Am I pregnant?

Wondering if you've got a baby on board? Pay close attention to your body! And if you spot a few of the following symptoms -- and your period is MIA - it may be time to head to the drugstore or schedule an appointment with your ob-gyn. The hormones released as soon as you conceive may start causing subtle changes even before they're detectable on a home pregnancy test. Unfortunately many, like sore breasts or bloating, also happen right before your period (a sure sign that you're not pregnant), so it's all a guessing game until you take a test.

2. Early Pregnancy Signs: Sore Breasts

This is a very common pregnancy symptom. Breast tissue is extremely hormone-sensitive. When progesterone and hCG start flooding the body after the egg is fertilized, they increase your blood volume, which makes your breasts swell and feel heavier than usual.

3. Early Pregnancy Signs: Cramps

You may feel crampy like you have or are about to get your period, but this pregnancy sign is actually triggered by implantation - when the fertilized egg attaches to the uterine wall. Your uterus may be stretching a little now (hence the cramps) to prepare for its massive expansion over the next nine months.

4. Early Pregnancy Signs: Spotting

Many women mistake some light bleeding for a period, but as many as 25% will have some spotting during implantation. If you notice that your "period" seems way shorter or different from usual, it may be a sign of pregnancy.

5. Early Pregnancy Signs: Fatigue

There's tired, and then there's this: If all you can think about at work is taking a nap or if you're too exhausted to keep up with everyday activities like hitting the gym, then it may be your body one of the earliest signs of pregnancy. Even at this early stage of pregnancy - within two weeks of conception - your baby is starting to use up your calories, which can wipe out your energy stores pretty quickly.
