If you're experiencing pregnancy symptoms, you're probably eager to know if you're actually pregnant — whether you've been trying to get pregnant for months or your pregnancy symptoms came as a surprise.
Early pregnancy symptoms such as tender breasts and fatigue sometimes indicate pregnancy. In other cases, these classic pregnancy symptoms might be due to something else — such as an illness or the start of your period. Often, the easiest way to know what's behind pregnancy symptoms is to take a home pregnancy test.
If your home pregnancy test is positive, make an appointment with your health care provider. You might also want to try a pregnancy due date calculator. If you're pregnant, estimating your due date is an important part of your prenatal care.(From Mayo Clinic)
