Implantation Bleeding?

I had unprotected sex for the first time with the Preseed Lube around the time I was ovulating. Now i see a little bit of blood when I wipe and it’s more of like a pink color. My period isn’t due until another week. I don’t want to get my hopes up or anything but when would I be able to take a pregnancy test? I’ve been extremely tired lately just wanting to sleep. Could this be implantation bleeding? Or my period really early? it’s super light though.
