Normal pregnancy after ectopic

Last year i was pregnant and suffered a ectopic pregnancy. I do not remember the symptoms except some sharp pain on one side. The pregnancy was terminated and i never followed up. Now i am pregnant again, about or around 7 weeks and i am extremely nervous. I have been feeling fine minus:
-fatigue
-swollen and tender breasts
-slight cramping discomfort on lower abdomen from left to right or right to left from time to time/
-integestion
-food cravings
-tired
-swollen lower belly
-nausea

I have my first prenatal appointment tomorrow at 8am but i gotta tell you i am almost about to chicken out in fear of what the doctor may tell me and not even show up or re-schedule.

my question is:
What is normal symptoms at this stage in my pregnancy? and is it possible to have a normal pregnancy after suffering an ectopic?
