Suggest Treatment For Constipation, Fatigue And Abdominal Cramping

I have been having a difficutly with bowel movements so I took some laxatives. This was about two weeks ago. Then a couple day ago I had to take more laxatives since my last movement was about 4 or 5 days prior. Now I can't have a bowel movement again. Some other symptoms I have seemed to notice is fatigue, gas, and stomach cramps. What do I do?Do I take another laxative? Do I try to wait it out? Could something be wrong with me?
