Cd 31, could it be?!

Hi all! I had my last cycle from April 5-9, 2015. About two weeks later I had 5 days of spotting. Had sex before, during and after my fertile time. Cycle was to start on May 2nd, 2015.

I am now on cd 31 and experiencing minor cramps, sore nipples, slight breast pain, nausea, extreme fatigue, minor acne.

I tested yesterday and got a bfn. Did I test too early?
