I m am 11 days late for my period and took 2 test that came back negitive. I have been getting nauseous, sore nipples, headaches, heartburn, and I have been really tired. Yesterday it all kind stopped except the nausa, I had some really bad pain in my pelvis. It s on both sides right at the front it seems to hurt much more I m sitting or laying down than when I m standing. Its kinda of like a burning feeling and it doesnt feel like i hit somethings its more like my plevis feel like its farther out in my body now. I can t see a doctor for 15 days and I m worried.
