OPK question

[brewco]

This is my first month using OPK's. . . I temped last month and FF says O was on CD18. Today is CD12, so what day would you start using OPK's? My cycles are normally 27-29 days. Thanks!

I usually O around CD 16-18 so I start testing on CD 13. Just in case my body wants to O earlier.

I would prob start on cd14 to give yourself some leeway since you've only temped one month and you never know what your body might decide to do.

i'll preface this by saying i use the wondfo OPK's, so i don't care about only using a certain amount since they're hella cheap.

i usually start testing about 4 days before i think O will be. if it's a clear single line on the test, i just wait and test the next day. once the 2nd line shows up, but ISN'T POSITIVE YET...then i start testing morning and afternoon. then once i get a positive, i test twice again the next day. usually it'll be positive in the morning and the 2nd line will be back to faint or gone by the afternoon. and by then, my temp spike as confirmed O with the test.

FF has an OPK optimizer under Analysis. My first month on OPKs, I started using them on CD 9 and O'd on CD 18, and FF yelled at me. This time I started on CD 12 and O'd again on CD 18. I didn't want to miss it the first time, and the month before was wonky and not see when/if I O'd.

I also use wondfo OPKs, so I don't care about "wasting" them.

I start at CD12 since I've O'd on CD14 and missed it one month completely.

ditto exactly.
