Not sure when I ovulated but my cycles are pretty regular and I'm due in a week or so. All of my previous pregnancies were clearly positive on tests early (8, 9 and 10 dpo respectively).
I got some Internet cheapies and dipped a few into a sample of urine. A few of them developed a very slight, barely imperceptible shadow after the time (normal for an IC). On one, the dye got stuck in the test line for a while but when it moved along it left a faint pink line within the time frame. It's too faint to even take a photo of.
Once I tested on 8dpo and it was a stark negative but over the course of the evening, it turned into a similar shadow than what I am seeing on these tests. I did a FREr when I saw the shadow on the IC and got a very clear BFP, so I do have an interest in what ICs are doing at this stage, even I'm if not really supposed to!
If you have any thoughts, let me know. I know to keep testing of course, but it's just nice to talk to other women about the testing madness as my husband thinks it's crazy lol
