Spotting?

So I started taking birth control two weeks ago and I got my period last Saturday and they normally last 6 days but on Thursday night I thought my period was done like I wore a panty liner and there was nothing on there and I wiped and there was nothing for 4-5 hours so I went to her and woke up and I wiped and still nothing and 2 hours into me being up and awake I went pee and wiped and it was blood...so I don’t know if I just started spotting and today I’m still spotting so I’ve been bleeding for 8 days and I’m kind of freaking out...
