Should I go for endometriosis diagnostic surgery?

Hello to all the wonderful ladies here,

I am new to this forum and this is my first post. Me(30) an DH(28) are married for last 5 years. We never tried to prevent neither tried seriously for first 4 years. Since last 1 year we are trying actively for baby. We went to FS and he did all the tests for me and DH. Everything came back normal. Did 2 cycles of clomid. Both unsuccessful. Now I am in 2ww wait for our first IUI. My FS said 3 IUIs, if nothing happened then IVF. He didn't do test for endo yet. I asked him and he rejected my thoughts. I want your suggestion that before going to IVF, should I push him to do endo testing? Just wanna rule out endo thing before IVF.

Any thoughts and suggestions please??
