Hi. I did not go to receive my third depo shot due 11/21 because of my insurance and my boyfriend and I been having unprotected sex since. I seem to be getting more and more symptoms as time progress like shortness of breath, cramping, and cramping if we argue and yell, sensitive to smell, foods that were my favorite taste funny now, no period still and Christmas is around the corner, nauseous, fatigue. Should I be worried that I'm pregnant or are these depo provera withdrawal?
