Pregnant again after ectopic pregnancy terrified 💔😔

First off I am excited but nervous. I had my ectopic back in December 2016 and just found out 2 days ago that I am expecting. They took out my left tube now I only have my right. Before I got pregnant I remember a nurse told me that my tube looked normal and it looked really really good. I’m still super early my hcg level is only at 19 so I’m only maybe like 2 weeks if that. No bleeding a little cramping but other then that it’s hard to be happy and excited when you don’t want to experience what you went through last time I’m just terrified and I just want a healthy happy baby and successful pregnancy. My anxiety is killing me 😔💔 I cant loose 2 babies
