If you are female, have had one or more children and are over 50, it is possible that your innards are sagging due to pelvic floor weakness - one of the most extreme symptoms of which is a prolapse.
It might be advisable to speak to a doctor about this. If you are referred to a specialist you may be deliberately misdiagnosed in order to protect against surgery overload because you are not in a very serious condition - that was what happened to me when I was referred to an ENT specialist. I knew he was wrong, wasn't in a serious condition but wanted at least to know what was wrong. Two years later after self-diagnosing I went back to my GP who confirmed I was likely right, sent me back to the same ENT guy who confirmed the test results and sheepishly asked if I had always thought this was it. He offered me surgery, I declined now that I knew for sure and told him I wanted to stay as clear of the medical profession as possible, nothing personal. He was nice enough to say he fully understood my position and said I was probably very wise to take it.
