Confused if I’m pregnant or not

Good morning

I’m really confused..

basically a few days ago I took a test the one that’s for 6 days early and I got 2 positives off of that but then when I did a digital this morning it said not pregnant.. I took it apart because I heard sometimes it don’t tell the right reading which I think has seen to be the case because when I took it appart there was 2 very clear positive lines. However after this I took a pink dye and 2 clear blues (the normal ones that aren’t early) and they have seem to come back with extremely faint lines that my camera can’t seem to pick up.. I’m 6 days late for my period, feel very nauseous and I am bloated

I am so confused

Why is this happening?
