I was told by a friend that if you get a negative opk right after getting a positive for e.g. from June 4-6 very faint opks and then on the 7 extremely bright opk and on the 8 faint again, that that means that the egg released and it’s showing negative now because the egg caught, is this true? I’m still not 100% sure how they work all I know is that they tell you that you might ovulate soon (within a day or too) I’m just surprised by how quickly it came and went I was under the impression that it would be positive at least 2 days before going back negative
