Faint line and now nothing?

Charlie🌻

Seeing if anyone has had this happen.

I’m not exactly sure when I ovulated, but I took tests on what I think was 6, 7, and 8dpo (based on when my partner and I had sex). I had faint lines on all 3 days (5 tests). I took tests again at 10 and now 11dpo and now I see nothing. Has anyone dealt with this? Did it end up being a chemical?

Thank you in advance!
