Scared to test

We have been trying for 15 months, and tomorrow is my day to test according to Glow. I haven’t had my usual PMS symptoms and I’m on my second round of 2.5 mg letrozole. I feel like I have a pretty good chance for a BFP, but I always feel that way. Anyone else get too scared to test for fear of a BFN?

My husband and I have had clear reports and should be able to conceive naturally but my doc wanted to try letrozole before she sent me to a fertility specialist. I’ve lost 30lbs and counting since last summer in hopes that would help. I’m getting disheartened by so many months of negative tests. I feel in my soul that I will be a mother someday but the process is getting depressing.
