Can an Ovulation Predictor Kit (OPK) be positive for for more than one day?
Levels of LH surge about 12-36 hours before ovulation takes place, before going back to normal. In theory, this means that you could detect this high level of LH from the very beginning to the very end – a period of over 36 hours! If you have a positive OPK for more than 3 consecutive days, your ovary may just be having trouble releasing the egg. This can happen if for many reasons (stress, illness etc) If this happens to you every now and then, it’s not a major problem. If it seems to happen a lot, talk to your GP.
