before xmas i started getting really emotional, crying at everything and getting moody. then i started feeling nauseous, which i have been now for about a month. im bloated, my breasts are sore and swollen. ive been gassy with heartburn. ive even experienced the light headedness off and on. im on birth control pills so i only get a period every 3 months. i went into the doctors 2 wks ago and took a test, the test was negative, the nurse told me to come back two weeks later if the symptoms persisted. that maybe the hormone wasnt high enough yet, that and i had peed like 10 times before i went there. if anyone has ever been pregnant, or know anything else this could be, please help. im scared and dont know whats going on. thanks
