Pre-Natal Bloodwork

I got my pre natal blood work done on 5/11 and the doctor hasn't called with the results. I'm going to call later, but does it typically take this long? She could also be a "no news is good news" kind of doctor which is fine by me, but do you think the results would be already finished? I know they do the blood and testing at the office so I can't imagine it would take over a week, but just wondering.
