Hi I am 29y/o. I have been having lower abdominal cramping for 9 days now, my period was due yesterday and I've had multiple negative urine pregnancy tests. I also had a urinalysis done yesterday, results unremarkable for leukocytes, rbc'c, etc... The pain worsened on my lower right abdominal area today radiating to lower right pelvis, constant dull cramp with occasional worsened "twinges" of pain. No rebound tenderness. I had an ultrasound today and am awaiting the results. I have had no fever, no weird discharge or smells, + nausea/Breast tenderness, fatigue, loss of appetite today, and no idea what this could be. Any ideas? I was sexually active 1 month ago, and he has a vasectomy
