Why do I feel this dull pain in my lower abdomen?

Ever since last week i have had this dull pain in my stomach and i feel very queasy and it bothers me 24 hrs a day. i feel and look very bloated too. i eat a very healthy diet and drink plenty of water, ive been having regular bowel movements. plus im so tired all the time like today i slept 8.5 hrs and then went back to sleep for another 2 hrs and im still tired. plus when i pee it seems likes all my pee sinks to the bottom on the toilet. thank you for any ideas
