need help figuring this out?

i got a OPK+ on 12/23 = CD 12 at 7pm.
today is CD29. When did O?
According to FF they said sometime between CD12-14 but mymonthlycycle is saying it was on 12/26?

sorry but this was the first month i used an OPK. (I should have continued to test the next 2 days to see if the surge was still there). thanks

Re: need help figuring this out?

when you get a surge on an OPK you can O anywhere from 12-36 hours after. OPK pick up the hormone that tells your body to release the egg, even if you tested after the surge you may not have had the hormone in your body.

So you could have o'd anywhere from 12/23 to early 12/25 approx.
Could have gone as late as 12/26 too.

DID you BD during that window and the days after? If you did, you have a good chance!

i'd be shocked but i'm thrilled for you! i think i'm second guessing the surge thing because i read that some girls get them for more than 1 day and I forgot to test the nite before so and didn't bother testing the night after the surge. The line surged pretty quick and it was def the same color if not darker. I had tested CD10 and got no surge.
