Please ladies I need your advice… 3 out of my last 4 cycles have been 31 days and the other was 35. I have tracked LH and saliva (ferning) all this cycle and I didn’t have an obvious peak, however there were some days darker tests than the other ie cd12 and cd23. My apps say I’m around 5/6 dpo however I’ve kept testing and my tests have been dark for the last 3 days (cd25, cd26 and cd27). Do you have any idea why this could be? FYI I’ve done a hcg test today and it was negative.
