Help tmi.

Okay so I found out I was pregnant almost 2 weeks ago and have my first appt Friday. I'm irregular but I'm guessing I'm about 6-7 weeks. I woke up this morning spotting and it's increased but not enough for a pad it's only when I wipe. It went from light pink to now red-ish pink. Now I'm cramping mildly. Could I be having a miscarriage?
