Hi Debbie,

I just wanted to pop in and say I've had the exact same experience with the exact same brands. My first month of using opks (now onto third month of using them) I found the fortel brand to be pretty crap for me. The second day I used them you could barely even see the control line so that did it for me, I don't use them anymore.

I use the confirm brand, usually at about 6pm and find that from about cd10 to cd14 the test line slowly gets darker and I usually get a definate positive at around cd13. This month for sure (and i'm taking clomid this month remember) I am positive the confirm opk coincided with all other o indicators.

Should mention I don't temp but have had bt's indicating that I do ovulate, probably at around cd14.

HTH!
