Had faint lines and now nothing? :(

I’ve been having some faint lines thinking I’m leading up to ovulation as I’m cycle day 12, did an OPK this morning and no line? My wee wasn’t very dark at all, in fact when I tested it looked like water. Could this be why? Do I test again? Scared now that I have actually missed my surge :(
