Two weeks late?!?!?

Jackee
Idk what to do. My period was due on the first of Oct. it's now almost the 14th. Took a hpt around the 10th with a bfn. I have zero symptoms neither pms or pregnancy. I'm at a total loss with this. I have pretty irregular periods but nothing like this before? Already have an appointment with my doc any advice in the mean time??
