could this be implantation ?

my partner and i had sex this morning but it wasn’t rough or anything, it was just a quick one. when i had wiped there was light brown, i wiped a few times and it was there. I went to the bathroom and i wiped again and it was light brown with a tiny bit of pink. ive never bled or anything after sex so it’s weird that it was brown. i’ve also been experiencing some light cramping…i’m only 6dpo. should i take a test or just wait it out til my period is expected?
