Brown spotting

Em

So about 1.5 weeks ago I had some red spotting once or twice when wiping. And now today I had some brown spotting when wiping only. I have my first dr appt next Wednesday but thinking I should go in earlier...anyone else in the same boat or have any advice? This is our first and went through a miscarriage at 5w in July. Keeping a positive mind because it doesn’t feel similar to how I felt in July and I still have pregnancy symptoms like tender breasts, bloating, food aversions & cravings and nausea / morning sickness. Currently 7w1d.
