Anyone here from Australia?

I'm just wondering if there's anything the doctors can test for in regards to TTC? My last Depo injection was January 2014. AF didn't come back till March 2015. We've been TTC since and keep getting BFN. Can my doctor help us at all? Do I qualify for Clomid? Originally my doctor said they can't do refer me to anyone until it's been 18 months. I'm not sure if that's 18 months of TTC or 18 months since Depo? I don't really wanna book and pay for an appointment with my doctor if she's just gonna tell me to be patient and wait. I'm sick of waiting, I want some answers! 😢
