When in your cycle do you get a LH surge on an opk stick?

Hello everyone,
Just started to try and monitor my ovulation using LH sticks. I am now at CD15 and still nothing - not even a faint line. (Don't have a clue what my cycle length is after years on the pill and a miscarriage. But last month I definitely got a strong line 13 days before my AF.) When does everyone else get a positive surge?

Hi LIG, my UCL is 25-28 days so I started using an OPK to test on CD10. As I have been using them for 5 cycles now I have had different days when the LH surge shows up. The past 5 cycles have been on CD14, CD11, CD12, CD13 & CD12. I am using the CB digital ones with the smiley face & I tend to either test before 9am (if the testing days fall on a day when I am working) or about midday (if on a weekend). Hope this helps. Good luck!

I've had them from cd 11 to cd17.
