Could this be implantation bleeding???

Only 5dpo, but I’ve been spotting the last 2 days, just a teeny bit yesterday, mostly brown, then today a little more. We dtd 4xs over the weekend so I was really hoping for a sticky bean. I’ve gotten a positive pg test at 7dpo with my second baby, so I know I can implant early, but that was many years ago and I don’t remember any bleeding. What do you think? I’m trying not to freak out because I had a m/c in March and I’m just having flashbacks to that. I don’t even know if I’m pregnant yet!! 😫 but this dark blood is freaking me out, and I’m having a little cramping. AF isn’t due until the 14th.
