Dear Megan, The first cardinal symptom of pregnancy is missing a period. The other symptoms or early pregnancy like nausea & vomiting with pica, frequent urination and breast symptoms like engorgement with tenderness, dark discolouration of nipples and areola with areolar widening, Montgomery s tubercles under the areola and secretions from nipples appear about a week after missed period. The home pregnancy tests may report false negative if done too early. They are reliable after about a week of missed period. So you may repeat the test after few days. Alternatively, you may opt for Beta hCG test which is highly sensitive and specific and gives reliable report even few days before missing a period. I hope this helps you. Dr. Nishikant Shrotri
