OPK pregnancy

Mu
Hi everyone 
I'm on cycle day 22 of 32 and I've been using OPK's for the 1st month and I got my positive on cycle day18/19 then went back to negative.
I have just tested again (same time as all the others this month) and the line is dareker then the test but not as wide? 
Does this mean it's positive again and can it be with 10 days to period?
