hello, i feel so pregnant, my boobs are larger and sore, my stomach is hard between my belly button and girl area, i feel cramping and streching like sensations as well as a full sensation, yet ive had negative blood and urine tests, but my last period was april 23 2014. I feel sick allot and my feet are sore easily, when tireness over comes me i cant handle being awake, yet im very hydrated. I swear im pregant but no positive tests yet, im starting to think something is very wrong with me if im not pregnant. please give me advice.
