implantation bleeding?

On the third i had pinkish spotting then later in the day turned more brown very light 
This is 3 days before my period 
The fourth agin light pinkish/brownish spotting 
The fifth same thing but this time a little bit of watery white discharge 
The sixth ( day im suppose to start ) 
I had alot of milkyish discharge like it was more white than watery but it wasnt really thick then later that day spotting again 
Then the seventh clear discharge, later that day spotting 
Is this implantation bleeding or very light period ?
