Here's an except from one site saying about the ovulation predictor tests. Ur not the only ones that thought it predicted the actual ovalation, thats y I did my research on it.
If an ovulation predictor test kit says positive, that means that I am for sure ovulating, right?
Ovulation predictor kits determine whether the luteinizing hormone (lh) is detected. The luteinizing hormone (lh) rises right before ovulation occurs. Therefore the kits are supposed to detect whether your going to ovulate but can not ensure that you do ovulate.
Women may have a high level of the lh if they have certain conditions such as polycystic ovaries, premature ovarian failure (pof), or for women over age 40 who are experiencing perimenopause. Any of these conditions could result in a false positive result on an ovulation predictor test.
