Early pregnancy symptoms are different from one woman to the other. A missed period is usually one of the earliest pregnancy signs and symptoms, though many women may have other symptoms too. Most pregnancy symptoms first show up shortly before or after a missed menstrual period and may include implantation spotting or bleeding, abdominal cramps, headaches, and lower backaches.

WHEN DO EARLY PREGNANCY SYMPTOMS APPEAR?
Small amounts of hCG enter the blood stream several days after implantation, about 8-10 days after ovulation and before a missed period. Therefore, pregnancy symptoms do not typically appear until the hCG has reached sufficient levels, about 1-2 weeks after you miss your period (3-4 weeks after ovulation, or 2-3 weeks after implantation). Though pregnancy symptoms may suggest that a woman is pregnant, a positive pregnancy test is needed to confirm a pregnancy.
