A little help please

Yes cd12 is positive. but you need to be testing 2 times a day between 11am and 8pm till positive both lines the same color or test line darker then control line whatever comes first is your positive so you don’t miss it. Your lucky you caught it. Ovulation can occur 12-48 hours. Opks don’t confirm ovulation or dpo. So if you want more accuracy add BBT to confirm ovulation and you will know when you ovulated, dpo, luteal phase length (is from the day after ovulation to period which stays the same each cycle give or take 1-2 days. Average length is 12-14 days give or take 1-2 days.) when period is coming by temp drop or if you miss your period and your temp stays up then there is a chance for pregnancy

Looks like you peaked on cd 12 which means ovulation could have happened anywhere from 12-36 hours after that, everytime you get even close to a positive make sure you bd! Baby dust❤️
