Feeling Disheartened

Samantha
I've taken 3 clear blue tests..
One Sunday morning, faint line..
Monday Morning again faint line..
Took another yesterday & the line was darker. 
I've read so much bad stuff about the blue dye tests. 
But my doctor says there's no reason for me to doubt a blue dye test. 
So confused 🙁🙁😫 x
Any advise ?!?? 
Please don't say "take a pink dye test"....
