I’m not very regular with my periods but I do know when they come and I’ve never had this? Usually I’ll pink spot constantly for 2 days light then start my period and usually break out in spots, and no cramps

Anyways Sunday night I had some light spotting? I’ll attach the pics below, do you think this could be implantation? I don’t know when I ovulated so... but it lasted about a few hours and I’ve not had nothing since, except cramping for 3 days just faint cramping tho doesn’t hurt or anything. Really hope it’s implantation 🙏🏻
