VFP and bleeding

I wrote on here earlier about this subject but I’m not sure on what to do now. This morning I got a VFP after a week of missed period and went to wipe after going to the bathroom and there was pink discharge? I knew it was blood but not a lot and definitely mixed with my discharge. I know the only thing I can do is watch it and see how long it lasts. It’s now brown and doesn’t have a flow. It’s simply when I wipe, does this sound like implantation bleeding or chemical pregnancy? I hadn’t had this with my other two pregnancies. Thanks!
