I’m now 18 DPO, and 4 days late. I took this test at 15 DPO and when I saw the BFN I assumed it was just a delay. I took a pic 4 min after taking the test to send my husband and he can’t see a line/ thinks it’s too faint to be true. I also assumed BFN but since it’s been 3 days since I took the test and no AF, I decided to try post here. I will retest next week to be sure but I’m so anxious living in limbo.
