Is this a positive pregnancy test?

[Arcoiris3101]

So my period was due Monday and on Saturday I started spotting, so I thought 'This is the beginning of my period'. By Tuesday, I kept only having the tiniest amount ot pink/brown blood which is kind of normal for me but then it completely stopped. Then, I realised that this could have been implantation bleeding. I didn't have it in my pregnancy and I didn't want to get my hopes up as I've done that before and it just ended in my period arriving.
Nevertheless, I did a test last night, I thought I got the faintest positive test. I did another this morning thinking it would be clearer, but it isn't really. Is this a bad sign? Shouldn't it be clearer? Or do you even see it?

Clear Blue are notorious for evap lines etc, I'd say try with a pink dye test. However I would usually expect your positive to be darker as you are late on your period, but you may have ovulated late! Either way I have my fingers crossed for you! X

For anyone finding this, it turned out to be in fact a chemical pregnancy.
