I’m tracking my ovulation to get to know my body more and prepare for trying for a baby in a month or two, I know the peak is when ovulation happens in a day or two ( correct me if I’m wrong) but I thought the levels would go down after ovulation I’m confused on why it went from 0.39 one day to 0.68 the next day??

Can anyone please explain??

( also had protected sex the day ( used condom but it broke but we also pulled out) of 0.39 thinking it was in the clear but is there a chance? We aren’t activity trying till aug/sept)

TIA
