Implantation bleeding ?

So my af is due 1/26 and for the past 2 days I've had spotting. Yesterday it was very light pink and only occurred when I wiped. This morning it was bright red a little heavier and still only when I wiped. Both days it was none in my underwear and I do not usually spot before a period. I took a test and its negative but just freaking out a little bit here!! I have no cramps and my period is usually heavy so if I spot it'll be in my underwear too so it's nothing I've seen before!!!
