It really depends on your cycle length. I have a 26-27 day cycle and usually start testing CD 8 or 9 and get a positive CD 11 or 12.

No most likely not, most ovulate around CD14. I recommend start using opks CD10 until you get your positive then stop testing. Once you get your surge you ovulate 12-36 hours later

I have have a 26 day cycle and just ovulated today on cycle day 11 good luck ttc 🤞🍀

I normally test 3 times a day .To ensure I don't miss my positive, and then my syrge. Here is my opk . This is what a peak looks like. Wait for this to happen then have sex the next 3 days . Worked everytime for us when we were trying to conceive. Baby dust
