CD 34, 23 DPO

Brooke • 25, Married to the man of my dreams since March 22, 2014. Now TTC my very 1st child!
Not sure what to do ladies! I'm in need of advice. 
This is my 1st time trying to conceive. I had Nexplanon removed at the very beginning of November and a normal AF arrived on November 6th and lasted the usual 5 days.
I used an OPK and determined ovulation to be on November 15.
Since then I have had a few symptoms, but honestly trying not to let that be a factor. ( I'm praying they are not psychosomatic) 
But to cut to the chase... 
As of this morning I am on CD 34, 23 DPO no AF ( I was due for it on Nov 30) and still getting BFN on Walmart cheapies (used my last frer last week and just can't bring myself to spend so much)
What do y'all think I should do?
Wait another week or so or go ahead and call the doc?
I'm slightly worried because I don't want to drink until I'm sure, but I know both of my families (mine and my husbands) will want to drink over the holiday season... And we are still keeping TTC under wraps for now.
