is this it ??

After having a miscarriage at the end of september , I taught my turn would never come , tested yesterday because all the symptoms are there ... and the test is positive YAY ! I then called my doctor and he started telling me off , i'm not due for my period until friday , he asked why did you test so early ?!?! And he says I might loose this one too and to not get too excited . Need some positive feeback please ? Any of you tested positive early and have little babies at home ! Crossing my fingers this is  it !!!
