Two miscarriages and pregnant

I'm finally prego after two miscarriages in the last year. At first I was excited, but now I'm just stressed and frustrated. I want to be hopeful, but I am just down today. I need to schedule an early first ultrasound, but I'm putting it off because I'm terrified. I've never gone to an ultrasound and heard my babies heartbeat. Every single one has left me in tears with a broken heart, and I don't think I can go through it again. I just want my own baby so badly.
