missadventure85:  I actually had this happen this month.  I had a CP in September and I didn’t think I ovulated this month but I actually did, just much later.  I noticed some EWCM and took an OPK that was really dark but not quite positive.  The next two days I had positive OPK’s, both super dark, much darker than the control line. 

When I tested again in the afternoon of day two of the positive the line had started to lighten.  When I looked into it, this is what I found “Once the ovulation test tests positive for the LH surge, it will continue to test positive throughout the surge. If your surge is two days long then you will have a positive ovulation test for 2 days in a row. After that first positive test, you can stop testing if you like. One true positive is all you need to know that you will be ovulating within 24 to 48 hours.”

I always get two days of them. Usually get my first positive in the morning, and the surge lasts until the following afternoon, so if I take them in the morning I’ll get two positives.

The hormone will be more ocncentrated in FMU, so if you’re taking it then that’s likely part of it.
