I’ve been tracking my ovulation for 3 months now and I was on 81 day cycle however last cycle was 35 days with positive OPKS on CD 24&25. The test line was VERY dark, the darkest I’ve ever gotten and this result was within a few seconds of dipping. I also did two other tests with different wees to make sure the test wasn’t faulty and all 3 had the same dark result

However, this one is tonight so within a day it has gone from extremely dark to extremely light. Does this mean I caught my ovulation exact on.
