Late ovulation

Christine • Mon, Jul 23 • Married 👰🏼🤵🏼 Baby #1 due April 2019 👶🏼🤰🏼🎀

This is the 3rd month my husband and I have TTC. According to the app, I am supposed to ovulate tomorrow but so far all of my OPK tests have been negative. Last month I ovulated later (I think CD21) and I have 28 day cycles. Has anybody ovulated later in their cycle but still successfully conceived?
