Help needed!!

So i used 2 clear blue tests, one with a single line if positive (10miu) and one with the cross (25miu) i dipped in same urine, the more sensitive has nothing on, but the 25miu has a definite line. The line popped up within 30 seconds! Clearly positive although looks lighter on the picture. Which test do i believe? :( Here's the positive one. Picture taken within 3 minutes
