Pelvic inflammatory disease

Does anyone know if past PID can cause an ectopic pregnancy? I am so paranoid. I am almost 8 weeks pregnant and about 6 years ago I found out I had PID which I quickly treated. What I am unsure of is can it cause an ectopic pregnancy even if you don't have it anymore or can having it in the past also cause it? I haven't had any pain or bleeding, just occasional mild cramping but like I said I am super paranoid and have anxiety so I'm just worried until I have my first u/s. I have 2 weeks left to wait :(
