Help! 6 weeks- test getting lighter?


I had a missed miscarriage last year at 10weeks and my anxiety has been really high this pregnancy while I am waiting for my first ultrasound. I decided to keep taking pregnancy tests every other day to help and reassure me. My test 2 days ago was basically as dark as it could possibly get, and my test this morning was definitely a bit less saturated. I’m trying not to overreact and freak out, but what do you think? They’re both FMU. 😕
