Am I or aren't I ?

Getting anxious and sad.  Only TTC for 2 months.  AF was due Thursday and I had not been feeling right since a week before.  Had naseau and dizziness.  Tested day before AF 2x BFN tested day AF due BFN.  AF now 3 days late tested today BFN.  I have very lighty tender breasts, gas, burping, indigestion, backache, emotional and irritable.  My normal cycle is 31 days and I'm 3 days past that but still BFN.  I'm frustrated because I just want an answer either way.  I'm not typically this late as I already have a longer cycle.  I've been using digital tests guess I'll just have to wait a little longer.
