Period or implantation?

I noticed in my panties a slight drop of blood and a lil dried looking blood around it. But when I wipe there is no blood what’s so ever. I’m 7 days late for my period and I’ve been trying to get pregnant. Is that implantation blessing or the beginning of my period? I really hope this time I’m pregnant after our miscarriage 3 years ago we really are ready to have our first baby!
