<s>[INST] I am a 26 year old woman with 2 children. Ive been on the depo shot for almost 2 years. For the past week or so, Ive been feeling a strange fluttering feeling on the left side of my stomach. I had a pregnancy test which turned out negative. I would just like to know what could be causing this. Thanks in advance for any info you can offer. [/INST] Hi. Thanks for your query. The fluttering in the left power abdomen may not be related to the Demo shot as you are having the Demo shot for the last 2 years. The possible causes in absence of a positive pregnancy test can be:Colitis of the sigmoid colon. Urinary tract infection, with or without stone. Mild intestinal infection. I would advise you to see a General Surgeon and get actual physical examination, investigations like ultrasonography and other relevant tests of blood, urine and stool. Further treatment will be according to the Physical findings and the reports of the tests.  </s>
