the waiting game

well about a week ago i started having what felt like light period cramps but my period doesnt start for another 2 weeks... then as the week went on my breast became sore and tender then this sunday i was trying to eat breakfast and i just couldnt get in down i felt sick right away so i went back to bed but i woke up later on and still felt nausea and stomach (like gas cramps)i went to dinner with a girlfriend and had to leave the table when dinner came because of the nausea by the end of the night i was running to the bathroom with uncontrolable diarrhea now today im back to having period like aching and cramps aching in my lower back also... I have really been craving breakfast foods ( omlets, french toast) the breast soreness has gone mostly now its kinda a burning felling in and around my nipples... I really dont think im pregnant but now i have two weeks till i start my period its really hard waiting to see...
