New with OPK and need advice please!

Hey y'all. Just got off pill after 2 months. I've used these in the past but never had luck. This is my first cycle off the pill. The tests have dried, within 5 minutes I was amazed... the test was double the color the control line on CD 13 & 14 afternoon. I'm wondering when I'll ovulate and how you can kinda guess your "peak" (I don't temp). This cycle I have been eating healthy, taking vitamins, exceeding, BD'ing every day of POS opk and have a good feeling. Looking for some input, thanks in advance 😊
