I know I have to trust, but

I'm getting really down today. I'm 6w3d after a loss at 10w in Feb. my symptoms have stopped and that's how it started last time. My ultrasound is Monday and I'm praying for a little love with a strong healthy heartbeat, but I know even then the journey doesn't end. My heart is already preparing for the end. I know I need to stay positive but is wrong to feel like I don't want hope to be up?
