This is my first month using an OPK after a few months of unsuccessful TTC - toddler in bed doesn’t always make it easy to make magic happen often.

So CD9-11 I got negative, then I got high from 12-15(today), which correlates with the calendar on here, but even after putting in that I got another high not peak, this calendar says today is my peak day to do the deed.

Is it supposed to adjust? Is it possible I missed the surge due to using FMU like the kit says but everything I read says LH is detected in the afternoon. Any insight would help! I really don’t want to miss my peak time, but my husband is starting to wear out on me 😂🤷🏻‍♀️
