Which OPK is my first positive?

Question

I don’t know if yesterdays test was quite positive but I know todays is, so I just need to know which is my first positive so I know a more accurate fertile window…

Answer

You go by the first positive both lines the same color or test line darker then control line whatever comes first is your positive.. Ovulation can occur in 12-48 hours. Opks don’t confirm ovulation or dpo. If you want more accuracy you need to add bbt to confirm ovulation to 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
