Fears after previous ectopic

Last year in may i had an extopic pregnancy that rupured in my left tube which led to the removal of that left tube. So now that ive been getting bfp's since the 19th and im supposed to be 4 weeks and 5days but i lost the last one at 8 weeks and 3 days. The earliest dr appt i cud get was july 25th but im worried that something will go wrong and it will be too late since my appt is so far away. Anybody else pregnant after an ectopic? I need help calming my nerves!
