Implantation spotting??

Last night I wiped myself and noticed a light pink discharge...I had very mild-I mean MILD- cramping for about an hour or so. Could this be implantation spotting?? I’m expecting to start my period in a couple days, but have never experienced this before...I did have sex while on my period so I’d be 4 weeks this coming week...🙃🤷🏻‍♀️ any insight would be much appreciated! Google/webMD tends to get one’s mind going hahaha
