My Stomach Has Been Hurting For 7 Days Now On

My stomach has been hurting for 7 days now on and off. I feel like I need to use the bathroom but only minimal amount will come out. My stool is mucous looking and my stomach gurgle's occasionally and I feel very light cramps. I did not eat nothing for two days consuming nothing but water. With no relief. I've only eaten chicken broth and crackers very minimal amounts but consuming lots of water. I went to the doctor Monday and she said she thought I had a stomach bug but I feel otherwise. I have no other symptoms.
