Implantation bleeding?

I apologize for asking this. I know someone posted about it but I couldn’t find the post. I had really really light bleeding yesterday (which was six days after unprotected sex) it was pink but obviously blood and kinda had like a clear mucus look to it as well. This morning I had a single drop of blood and when I wiped it was the same thing pink with the clear mucus look mixed in. Is that implantation bleeding? Usually when I spot (which is very rare) I have more blood than that and it’s never looked like clear mucus also. Is it possible that was implantation bleeding? Thank you in advance!
