Is running still okay?

I found that I was pregnant just a wake-up call so from my last menstrual I am 5 weeks along I will see the doctor on Monday my question is can I still run I've been running for years and then stop for a while last year due to injury but I've been consistent the last 3 months I was told by so many people including my friend who's a registered nurse that I shouldn't be running until the second trimester but I see so many women continuing their workout regimen should I keep running or wait for my doctor's appointment?
