Anxiety preventing BFP

Rose

We suffered our second chemical pregnancy last month. I was so stricken with nerves the entire time from the moment we got our bfp, for fear that it would end up like the first chemical. Sure enough, it did and I’ve been distraught since. Im just wondering if my nerves and anxiety are causing this to happen. What does everyone else do to keep calm during their pregnancy? I’m having the worse time coping with this.
