I took this test this morning. The faint line showed up 2 minutes after dipping the test into the cup. However I'm worried it could be a faulty test. I took it because I bought in bulk off Amazon and just got them yesterday ( I got excited and just wanted to take one) but was very sure it was going to be negative. I say that because I'm either 8 or 11 dpo and according to this app I'm 8 days away from af's arrival date. ( I have 32 day cycles.) I feel like a positive wouldn't come this early because with my son it wouldn't show up until I was 6 days late and I took about 20 tests with him because I knew they were wrong.
