    OPK Shows LH surge for 4 days - what does that mean?

    I started testing on Day 12 and the OPK surge line has been strong for 4 days now. That doesn't seem right, doesn't it? Does that mean a false positive?

    Do you have PCOS? That can cause a false positive...Are they really positive or just really close? I've gotten a few around the time of the actual surge where they were *almost* positive but the test line has to be as dark or darker than the control line...

    Good Luck!

    This cycle I got a + on Sun pm, Mon am & pm, and Tue am. I guess that really was only 36 hours for me though. I'm not really sure. Hopefully one of the gurus can answer for ya. Good Luck!

    Hi there: It's very common to have more than one day of ++OPK ... many women stop testing after the first day so they are unaware of this ... I know I've seen 2-3 days of ++OPK without there being an issue ...by 4 days I'd expect to start seeing the surge disappear ...

    What do the OPKs look like? When you say "strong" lines, are the result lines the same or darker than the reference lines?

    I'll check back++++++++++++++

    I pulled this out of an article I was reading off another link I found in reference to a different question I had....

    A hormone called lutenizing hormone (LH) peaks in the blood and urine one to two days before ovulation, at the onset of the most fertile period in the cycle. The length of the LH surge varies from woman to woman, lasting between 10 and 31 hours in about half of women, less than 10 hours in 38 percent, and over 31 hours in 12 percent. Research has proven that LH surge is among the best indicators of ovulation, and the kits that Consumer Reports tested are based on LH measurement.

    Hope this helps!
