Bfp after miscarriage but worried

As

At 36, I misscarried my first June 1st at 9 weeks. Resumed iuis and have a bfp. I tested yesterday at 13dpo with a frer and easy@home test. This morning I only tested with easy@home and I feel like my line is lighter. It's craziness and I have reassured what feels like millions of other people with diluted urine, don't test consecutive days, hold length, etc. Yet here I am in a full blown "this is going to end badly" state.

Top test is yesterday (dry) bottom today (half dry)

Here's the test and frer from yesterday. I will probably use the other free I have tomorrow.
