Missed period

Hey ladies, 
I miss my period completely for Nov. Took a test after missed period bfn.  If I'm back on cycle af should be here around jan. 12th.   
My husband and I did the BD on dec 27th unprotected. Should i wait until af should be here in January or should I test now? I haven't really had any symptoms except yesterday I had light pinching in my left ovary.
