Hey, first OPK use confusion??? I got this result, on first day after end of (6 days long) period (so cycle day 7). I have irregular periods. Any ideas how soon you can ovulate after period?? I am just surprised at how dark this is, for so soon in cycle. I check CM too, which says not fertile yet, but not sure about this opk result and timings etc?!?! Can't find answers anywhere! Thanks ladies. :) :)
