POS addict MC anxiety

I have to tell myself to stop I have been testing daily as I have had multiple miscarriages. I do have a healthy almost 2 year old and pregnant with hopefully baby #2. Which will be my last. It was so hard getting past the MC anxiety with my little boy and I'm feeling it all over again. How do you just stay positive and stop yourself from worrying, is that even possible. I want to enjoy every bit of it but I've been letting fear get in the way. Anyone else get where I'm coming from? Heres my line progression from 13 dpo to 15dpo today (top)
