somebody please help me..

Last week I took a pregnancy test and the line was so faint so I waited and I took  pregnancy test and there was a line forming and after 5 minutes (the test said wait 5 minutes) I took the pregnancy test apart to see if there was any dye run and to really see this line, there was a second line I've got all my hopes up, I had a miscarriage 2 years and 8 months ago and this month my baby would of been due, somebody said that when you take a pregnancy test apart the test is invalid but I waited I didn't do it as the line was forming....what should I do. I'm so upset and confused my hopes are up so high. I'm confused.. please ladies help
