Ttc for 4 years

Me and my partner have been together just over 4 years and been trying for 4. We’ve been together since we were teens and have known each other our whole lives. I know that he’s the man im supposed to have babies with. He’s got 2 children from a previous relationship, which is amazing because I get to be step-mum! But also kind of heart breaking at the same time thinking I’m never going to have a baby. I’m writing this now at 7:55am having been up all night with anxiety and just sobbing because I feel like a complete lost cause. Anyone else had extreme difficulty? We’re about to move house so holding off on the docs till we sign up to new surgery (don’t want any appointment letters going to old house)

Just wondering if anyone else has had to wait this long and actually conceived naturally? Thanks ❤️
