Please help a sister out.

The pic shows my LH tests from Aug 20 to 25. I feel like I never peaked, and test line’s almost gone Aug 25. Tested again Aug 26, same result as the day before so I did not bother anymore.

Question:

1. Is it possible to still ovulate this cycle given that I was pretty positive but did not peak Aug 21 and test lines became fainter and fainter then? I didn’t test yest and this morning since I was losing hope already. Should I keep testing??

Other facts:

1. No egg white-like CM. Only milky white discharge since yesterday.

2. Lightning crotch today (if that matters haha)

3. Last cycle I ovulated CD 19 (based on app because I only used OPKs this cycle)

4. Today is CD 17
