Feeling discouraged, am I out?

Brielle • 30. 👶🏽💙 8/2020. 👼🏽 12/2023. 🤰🏽💜12/2024.

Same chart via Glow and PreMom. My temps kept going up until 10 DPO (BFN) and began dropping yesterday at 11 DPO. Am I officially out? Should I expect AF to begin soon? Too scared to test today due to fear of disappointment 🥹
