Pain 2weeks before period

Logan

I have seen an Endo doctor and they took lots of labs. Everything came back normal. I had really bad shooting pains about 2 weeks before I was due for my next period. Is that a side effect of Endo? They won’t be able to tell I have it unless I give them the green light for surgery. I don’t want to have surgery if I know I don’t have it. Any advice would be greatly appreciated!
