Placenta previa?

Diagnosed at my 20 week ultrasound with complete placenta previa? What should I expect going forward? I need to wait to see the specialist on Monday but the nurse called after receiving my ultrasound results to advise me no intercourse, penetration, even vibrators, and to go to labour and delivery immediately with any bleeding at all. I haven’t had bleeding and otherwise feel good! Feeling nervous, just looking for experiences!
