I've never been pregnant and don't plan to be for many more years, but this may help.

Some early symptoms of pregnancy are:

Tender, swollen breasts - Your breasts may provide one of the first symptoms of pregnancy. As early as two weeks after conception, hormonal changes may make your breasts tender, tingly or sore. Or your breasts may feel fuller and heavier.

Fatigue - Fatigue also ranks high among early symptoms of pregnancy. During early pregnancy, levels of the hormone progesterone soar. In high enough doses, progesterone can put you to sleep. At the same time, lower blood sugar levels, lower blood pressure and increased blood production may team up to sap your energy.

Headaches - Early in pregnancy, increased blood circulation caused by hormonal changes may trigger frequent, mild headaches.

However these symptoms aren't unique to pregnancy so the only sure fire way to know if you are pregnant is a pregnancy test.

Most doctors recommend that you wait until the first day of your missed period before taking a urine pregnancy test. This is usually about two weeks after conception. However, some tests are more sensitive than others and can be taken earlier.

A blood test can detect a pregnancy earlier than a urine test at about 7-12 days from possible conception (but if a negative result is received, a test should be repeated if a period is missed.) However it is more expensive than a urine test (price depends on cost of doctor's visit and lab fees).
