OPKs and Faint Lines...Progression???

[wlovew]

I know in order for an OPK test to be *positive* the line must be as dark, if not DARKER, than the control line. Ok, so I test 3x/day starting at CD5 (better to be safe than sorry with a cycle like mine of 24-31 days!). Every day so far has been totally blank. Starting this morning CD9 I am getting a faint line. So I'm wondering if perhaps the LH is beginning to increase now?? This morning it was blank, this afternoon I got a faint line. Assuming this evening it will be a tad darker. BBT has been dropping steadily the last few days. Did an insemination last night to be on the safe side, and will do 3x more this cycle as I track the heck out of my ovulation lol Last month the OPK tests weren't here until CD14 and I got some lines but none were as dark as the control line. I had done an insemination CD14 and CD16 but I was too late I think. Or maybe I was too early??? AF did not show until CD30. BFN's suck !! Being quite the newbie at this I am still figuring everything out. Thank GOD for FF!!!!
