Oh no! Faint line disappeared?

Ashley • Astrophysicist TTC @ 33. Oliver & Alessa born/passed Sept 2008. Emma born Aug 2010. James stillborn Jan 2015. Sarah born Jan 2017.

Getting faint lines regularly until today. Praying this isn’t a chemical after 7+ losses. Possibly 8-9dpo today, and I always implant and get positives super crazy early. Help! What do you think?
