My daughter just got her passport in TWO WEEKS, non-expedited. Just regular service. I was amazed! She had an expired one from before, and there was no rush for the new one...but it was very fast.
Did you include your email on the application so they can send you updates? Or if not, you can still track the status on the Department of State website. Easy to find the link, just google US passport status and you'll find it.
When are you traveling? There are resources to help if you don't receive it in time. Honestly, I think you will get it quicker than you think. Good luck!
