I know it’s too early to test but I’ve been so crampy and have constant lower back pain for a week now. My cycles are between 28-35 days long so my O date probably fluctuates some. Not actively TTC so I don’t track closely. Planning to retest this weekend or early next week when I’m between what I think should be 11-14 dpo. App says period is due in 9 days. First pic is within the rest test time and 2nd pic is next day. Can’t tell if it’s a water line or if it’s a faint line.
