Trucey,
You are most likely pregnant, home pregnancy test are about 99% accurate. Your friend that has the daughter most likely took the test too soon and thats why it showed up negative. So you need to tell your mom that you are pregnant and go see a doctor to find out how far along you are and such. I know it will be difficult, but we are all here to support you at this website, so let us know how you are doing.
With much Love,
Falon
