Past ectopic pregnancy

Hello all! I am about 5 weeks and 5 days pregnant, and I have had one miscarriage 9 years ago and an ectopic pregnancy in October 2014... I only have one ovary and Fallopian tube, so when I had surgery to remove the ectopic pregnancy, my doctor spared my tube. We finally got pregnant again!!!!! We are elated!!!! But we are so fearful! My first appointment is tomorrow morning and I have been hoping and praying that this is a viable pregnancy. I am SO SCARED this will be ectopic again because of the damage to my tube from the surgery! I know my ultrasound will be too early to see much of anything, but I NEED to see a pregnancy in my uterus. I will be so devastated if it's tubal again.  Has anyone else been through this? The last 24 hours waiting to go to the doctor is becoming so difficult!
