Pcos, clomid, cd19, faint bfp... Too early?

I'm on Cd20 of my 2nd round of clomid. I done a test yesterday and not even a hint of a line. Done one this morning and straight away seen a faint faint line, I spent about 10 minutes looking at it from every angle and it was definitely there but super faint. I wanted to look at it again so a couple of hours later I took it out the bin and the line was darker, I even dropped a bit of water on the strip because I heard if you do that and it's an Evap it will disappear and it just got more obvious. I don't know what to think. I've never seen a line this obvious since I got pregnant with my son but could it have started out very very almost invisible and then get darker? Or is it a no?
