You're bloating, cramping and riding an emotional roller coaster that has you crying one minute at the sight of a new puppy and being irritated by the way your partner cooks spaghetti the next. You're expecting your period to arrive any time now. But it hasn't.

Could you be pregnant? Four weeks is the right time to find out by taking a home pregnancy test. Home pregnancy tests are a simple, fast and accurate way to confirm your suspicions. The tests can diagnose 90 percent of pregnancies on the first day of a missed period by measuring the amount of human chorionic gonadotropin (hCG, the pregnancy hormone) in your urine. Even if the test comes back negative, it doesn't necessarily mean that you aren't pregnant. It might just mean that there isn't enough hCG in your urine yet. Levels of hCG double every few days, so you'll want to take the test again to be sure.

This may be a surprise to you -- or not. Some women recognize early pregnancy symptoms as being just that. Others swear they knew they were pregnant the moment they conceived. Still others might not truly believe they are pregnant, even when presented with the facts.

At week four, you're at the beginning of what is known as the embryonic period and you're already a third of the way through your first trimester. What should you expect and how should you adjust to this life-changing news? Keep reading to find out.
