I think my OPKs are getting close to peak.  They got darker today from when I tested at 2:00 til testing at 8:30.  It's my first month using them so I'm learning.  I'm on CD10.  My body is still adjusting from going off the pill (unless I'm going to have irregular cycles).  My first cycles were 28, 26, then 38 days.  Should I keep testing twice a day? Or add one in around 10:30am?  I just don't want to miss my surge so that I can best track my cycles.
