I’m wondering if anyone has any experience with invalid OPKs – ones with no control lines at all. In my current batch of cheap tests, I’ve had three invalid tests in a row. Usually in a cheap OPK or pregnancy test, you can see the dye spread from one side of the test to the other before the lines begin to appear. That didn’t happen – it was like I hadn’t dipped it at all.
Is there any way that I could have caused this? Or should I contact the seller and tell them they’ve sold me something faulty? They were really really cheap (50c each).
