im not preagnet or I cant get I've already had my tubes tied & burn so why do I feel things in my stomach
It might be, or it could just be your normal digestive processes - the gut moves quite a lot when it's working properly, but sometimes we don't notice it. Once you've become aware of it, you do notice it more, and then it sometimes gets worrying! Do ask a doctor if it seems like more than the usual digestive activity.
I'm not sure but it definitively doesn't sound normal - you need to make a visit to your doctor, it could be serious.
