Spotting 3DPO implantation

So let me start by saying I NEVER spot. Not even before or after my period. Anyways, I did feel like I was having a little more discharge than normal since at times I could actually feel it or whatever. Anyways, went to change my liner (because I like my underwear to stay pretty and I get a good amount of cm before/after ovulation) and noticed there were some spots of pink?? My husband and I haven't been having rough sex, quite the opposite so it can't be that. Nothing explains it other than possible implantation? Though I thought it was super early for that 🤷🏻‍♀️ any insight?
