i am taking a HPT in the morning but if it comes up negative what in the world is causing the pregnancy symptoms??? hot flashes, constipation and gas, severe mood swings, heartburn/indigestion, a little more attention to food tastes and things I really want that I usually wouldn't (just noticed this today and it is very VERY slight), gained 4 pounds, somewhat tender around my breasts... anyways you get the point. would the Lupron cause my body to do this without being pregnant??? NEED TO KNOW SOON PLEASE!!!
