Nervous

My husband and I have decided to try for our 3rd. I’ve miscarried twice since our youngest was born in 2018. I’m scared I’ll never have another successful pregnancy. I tried to talk to my husband about it but he is very reserved. I just keep thinking how I’m almost 30, have a BMI of 29, and have had two miscarriages. I am scared that I’m setting myself up for failure and disappointment. I don’t have a question or anything, just needed to get it off my chest.
