Home pregnancy tests are normally performed at home after the date when the menstrual cycle is supposed to start. Symptoms may include implantation cramping and spotting, nausea, vomiting, and breast tenderness. The increase in the pregnancy hormone triggers most of your early pregnancy symptoms which can be an indication that you might be pregnant. What are the most common early pregnancy symptoms? It's rare to have a false positive pregnancy test (a pregnancy test that's positive but you are not pregnant). It's much more frequent to have a false negative pregnancy test (a negative pregnancy test when you are actually pregnant). If hCG is present and the pregnancy test is positive, then there is a high chance that you are pregnant. This hCG hormone is produced by the placenta and usually shows up first in the blood within 2-3 days after implantation and several days later in the urine. Download Now!
