I'm confused... Don't know if im actually pregnant...

Marlene
I went to my gyn for a regular check up. So i told her i want to take a pregnancy test. Im thinking it was going to be negative and long and behold it's positive. But it look very faded the second line. Im suppose to get my period today and nothing. So i brought i pregnancy test and it reads negative so im confused... the only symptoms i have are my breast are a little tender. But that's about it. The doctor said that im very early. So if i am why isn't showing up positive? Should i wait a couple of more days? Could someone help me with some feedback pls...
