Spotting

So I had my first obgyn on Thursday with my high risk dr and at that visit I started spotting very lightly (picture below) and i thought it was the start of another miscarriage. I’ve had 3 miscarriages 2 of them started with spotting then full on bleeding a couple days later. But this time I spotted Thursday which was the day before AF was supposed to show up and haven’t spotted again. I’ve been on edge scared Im gonna start bleeding at any time, but I haven’t. My 2nd blood draw is tomorrow. I just want to know if I’m in the safe zone?:/ if I was gonna miscarry would I have fully started bleeding already?
