I need advice !

So I have endometriosis. I’m 27. I have never been pregnant... not once.

My reproductive endocrinologist who has been following me for 10 years after being diagnosed with stage 3 endometriosis did lab work after me ttc for 1.5 years without anything happening.

My AMH or ovarian reserve dropped from 3.5 in 2013 to 2.2 in 2017 and now it is 1.7.

He is concerned about early menopause for me.

He stated, if she wants to have more than 1 child I recommend going straight to IVF and skipping IUI.

I would ideally like to try at least one round of IUI. See how that goes then maybe do IVF.

Please if anyone has experience with this, give me guidance. Idk what to do
