Pregnant a month after ectopic, left tube removed. help

So I found out I was having an ectopic middle of July 2017, the shot didn't work, my left tube ruptured and it was removed. I just got a positive pregnancy test last week. I never even got my first period yet. I got blood work this week 82 hcg 2 days later 230 hcg, so I am pregnant. I have an appointment tomorrow at 2, I'm so scared I'll have another ectopic or miscarriage especially that it's like a month later. No bleeding, cramping. No symptoms. Has anyone else gotten pregnant after ectopic this early and have been successful? I'm freaking out
