Implantation bleeding

Jenna
Ok so I'm due on my period tomorrow, the last few days Iv been feeling queasy and having light cramps and sore boobs. 
I was working away today and always panic that I may come on while I'm out so I used a tampon just incase, when getting home and removing the tampon there was a tiny bit of blood but it was a super light pink, could this be implantation bleeding? 
Should I test now or wait a few days? 
I really really hope this is the month for us to have the great news, the wait is horrible, praying AF don't show tomorrow 😖
