A chemical pregnancy is a pregnancy loss that happens very early, often before you realize that you're pregnant. The only sign may be a late period, though a very early pregnancy test may have shown a faintly positive result. In a chemical pregnancy (sometimes called a chemical miscarriage), the egg is fertilized but doesn't completely implant, and the embryo stops growing. Chemical pregnancies are very common, and they're not a sign that you'll have trouble conceiving again. But they can be emotionally painful, especially if you've struggled to conceive.
