Super light pink spotting after sex?

Me and my partner just got done having sex and I wiped and there was light pink spotting, not much of it and now when I wipe I see nothing. This has never happened before so i don’t think it’s anything to do with the sex since it wasn’t that rough it was just...usual. My period is due in 5 days could this be implantation? If it is will a pregnancy test show it?

We aren’t trying so I’m freaking out a little.
