Confused on spotting

So my period was due 2 days ago and it been pretty regular well the day I was due I spotted twice and very little then yesterday nothing and now today some light spotting but this time a little on the pad could this be anything or just weird period?

Also about a week back I took a home pregnancy test and came back faint line then took another the next day and got 2 negative test so I assumed the faint line was a false positive but I am now wondering whats

going on

The photo is of my pad of what I have spotted all day which is not much

The photo with the faint line is not the best picture but the vvfl had pink to it
