Help confused 😩😩

It might be TMI but maybe someone has an answer.... so I have irregular periods and got my period January 17, 2018 - January 21, 2018 so my normal 5 days yesterday I had very light pinkish spotting and today January 25,2018 it looks like I'm having a very light period ..

What could this be ? Not my period again because it's too soon
