Need advice

What all should I be making sure my OBGYN should be doing or testing while I’m TTC before I get referred to a infertility specialist?

I track my ovulation I get positive ovulation test…

We try and have sex every other day after my period ends until I get a positive ovulation test…

My OB doesn’t take me serious unless I tell them what I want but I’m slowly giving up and don’t know what else to do..

I spot 2-3 days before my actual period starts. Is that normal? Idk what’s normal and what’s not. Or is that low progesterone?

I have figured out that I ovulate on cd 21-22

I feel like I’m slowly losing my mind… and every cycle it’s me saying “maybe next time” and then 3 years pass 😩
