So upset!!

So did a clear blue test yesterday and got a '+' which was very very faint but definitely visible which my OH agreed also. So figured I'd retest today, bought clear blue digital one and also first response one, both came up negative, first urine of the day as well! Just so so upset! Tried to not get my hopes up last night but I really thought I was going to see a positive! 
Been trying since June 2015 (when I came off my microgynon pill) and nothing yet! Last night is the first time I've ever got a positive result! But I heard blue dye isn't that great! Looks so much like a positive though! Getting really upset and down each time I take a test and see BFN! I mean come on we really want this & have been trying EVERYTHING! My periods are irregular but I did a ov test a little while ago and got a positive so we BD'd so so much over that week. Even still any other day we pretty much do it every day!
Am I right or wrong in losing hope? I just need more hope sent my way! And baby dust! We're desperate for our own baby & it's so upsetting it not happening for us!! 
Ps. Wishing everyone good luck who's on the same boat as me! X
