Miscarriage help

An

I had a period that lasted 8 days, and I felt funny all throughout the 8 days (symptoms that were more like pregnancy symptoms than pms). On the 8th day (Thursday) I took a test and got a faint positive. It’s now Sunday and I’m still getting the same exact faint line. Sometimes it’s lighter, but then it goes back to being as dark as it is in the pictures, but never gets darker than that. It’s usually lighter in the morning, and in the afternoon it gets darker. But then the next day it’s the same thing.

My question is, was my period the miscarriage and it just takes a while for the positive line to go away? Or have I not actually miscarried yet since I’m still having a positive pregnancy test? I’m planning on calling my doctor Monday. Just curious if anyone on here has any experience with this. I’ve had a miscarriage before, but it was at 17 weeks, so it was obviously very different.
