I think this is more normal than anything- endometriosis has a nature that is more organic than not. It is more unlikely you would have symetrical swelling, in my non-doctor, laymans opinion.

Yes! I have notice that my left side sticks out more. Because if I have a tight shirt on its very noticeable. I am not sure why it does it though. But all my problems are on the left side so I figured that would be why.

Hmm I have not notice that. It all seems the same amount of bloatedness for me
