Etopic Pregnancy Symptoms?

What are symptoms of an etopic pregnancy? I have my first doctors appointment this week but I've been having the past few days cramping, a burning cramping sensation in my lower abdomen near my pelvic bone, my sides I've had a bit of cramping. And near my (tmi) crotch and butt a sharp pain. Is this normal for 8 weeks? Should I bring this up with my doctor?
