Faint lines..

Al
I've taken two tests and they've both come out faint. Some are saying positives some are saying it's an evap line. I'm also three days late. I've still had cramps like as if my period were to come but that's it. 
I'm not sure where to go from here. After work I plan on buying some pink dye HPT since those have been suggested a lot. 
Any opinions or suggested would help :) thanks ladies and baby dust to all off you TTC ✨?✨
