Ladies please help! Just started spotting tonight!

I am 6w2d today and just started having light brown spotting when I wipe. I have an appointment tomorrow at 4 so I don’t feel like I need to call before then. I’ve also had all day nausea all weekend and have barely been able to force myself to eat anything. I had a miscarriage in September and am really hoping this one sticks! Is this normal? Any advice to ease my mind?
