5 weeks 1 day spotting?

Okay so, I'm 6 weeks and 1 day according to the apps I have since I haven't had my first ultrasound. I have been on light rides at Disney, keeping careful as I don't wanna risk anything, this morning I had some light, brown spotting only there when I wiped. Absolutely nothing the last 2 days at Disney. I also have light cramping here and there which has been happening for weeks but it once in a while gets a little more painful. Is this likely a sign of early miscarriage? I'm so nervous.
