Staying hopeful

My first and only pregnancy ended in miscarriage at 8 weeks. This was 8 years ago and I have been petrified to go through that again. I am a newlywed and my husband and I have recently started TTC. Even though it's just our first cycle of trying, I feel overwhelmed with fear that we will have difficulty conceiving or that I will miscarry again. Does anyone have any advice on letting go of fear and holding on to hope?
