Ok, did a test this morning this time using a "pink" tester rather than the "blue" which can give false results due to evaporation lines blah blah blah.
The test came up positive within seconds!!!! Think I can safely say this is a definite positive. AF due tomorrow but couldn't wait, lol.
Thing is I'd stopped trying, after no luck over the last 3 or so months (I usually catch really quick) hubby and I decided it wasn't meant to be and he even convinced himself it was for the best. Strange how things work out, hey.
Will do another test tomorrow and as long as it gives the same result then it's a call to the Dr on Monday :)
