Irritated/anxious

Kaylee • Married Oct 2002. Birth doula. Expecting #4.
So today marks 3 weeks since I had my Harmony blood test done and I still haven't heard anything from dr office. I just called and left what was probably a pretty nasty message but this is ridiculous. There is no way in the world this takes 3 weeks. Either there's a problem and they are lying when I call or someone screwed up and they never even submitted my blood test or the lab lost it or something.  I'm freaking out here. I'm leaving the country Friday at 6 am and I need to know before I go that everything is ok.  Feel free to tell me I'm being crazy but I needed to vent.
