Dreaded..two day wait?

Just started bleeding out of nowhere while my fiance and I were knockin boots and my period isn't even due for 4 days. It started off red but there was barely any and now it's just light pink. I honestly can't tell if he started my period early or if this is actually implantation bleeding (which I noticed something that also could have been implantation bleeding a couple days ago). I'm 10 dpo and 4 days out from my period. Now I just have to keep an eye on it for a couple days and THAT'S gonna be the hard part🙈 already been checking every two minutes😭
