Anyone else with same symptoms?

Was suppost to start af last Friday and nothing yet so 6 days late and nothing. For 7 days I have been cramping dizzy a tad but of discomfort in right nipple my back is hurting I do not have a appetite and I'm slightly nauseated at times not constant though. We are ttc #1 but I've taken several hpt like 11 all negative. I feel like everyday that my period will come at any moment but nothing. I just got through with a heating pad because of cramps my right side is hurting every once in awhile. I called doc to come in the morning to get a blood test done.
