I had my tubes cut tied and burned 7 years ago but now i feel movement in my stomach?

Possibly pregnant: Tubal ligation is the most effective contraception but it's not 100% effective. Pregnancy after ligation is called "failure". Failure rate varies according to the study. One of the largest studies reported an overall failure rate over 10 years of 1.85%.(between 1 and 2 patients out of a 100 got pregnant after ligation) Pregnancy after 7 years less likely but possible. Could movement be imagined??

Pregnancy unlikely: Very unlikely to be pregnant but not impossible. A home pregnancy test will say for sure. Another cause of your symptoms might be gas or stool traveling through your bowels.

Small intestines are: constantly moving; fundamental to digesting food: both continuously mix food & water secreted from blood stream (~7 liters/24 hrs) with digestive protein enzymes secreted by both pancreas & cells lining intestinal walls. Different portions of the the mix must constantly be exposed to the intestinal wall cells for selective absorption of what the body does/does not want to absorb vs. excrete.
