Faint pink line 10 dpo, day later no line

Ashleigh

Hey everyone! I’m completely new to this and it’s TTC#1. I took a test yesterday morning (10dpo) and a faint pink line appeared within 2 minutes. No picture, sorry. I went pee Before I went to sleep at midnight. Today ( 11 dpo) Woke up at 3:30am and retested (was excited) and it was a BFN. Woke up for the day at 9am and still BFN. Is this likely a chemical pregnancy, or too diluted to detect or what? Decided I won’t retest until missed af.
