I feel tired all the time. My breast are kinda sore. When im walking up stairs i feel weak and my body feels heavy. i feel really boated alot especially after i eat something.I feel nausea most of the time on and off but no thrownig up. My stomach some times feel weak. I feel movement in my abdomen but i cant really explain it. All i can say is it feels like somethings dropping inside of me. I Have water-like oderless discharge. Without burning or itching. I get cramps in my stomach when i run. Im always thirsty. My face is breaking out really bad but i dont dreak sodas are eat candy anymore. All i drink is water ALOT!(im always thirsty) Could this mean im pregnant? Or What? I really need to know!! Can anyone assist me with this problem?
