Someone help please?Implantation bleeding?

Morgan • Army wife💕 the best son

So I had unprotected sex about a week ago a few days after my period stoped around the first few days of February.

I went pee and noticed I had light bleeding but barely any.. kind of a lighter red pinkish . But I don’t know if I would have it this soon it’s been about a week since the sex.i just don’t know how long I can wait to take a test google doesn’t really help with my questions.
