Ovulation help!

My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> say my ovulation peak is on the 30th however I did get a positive OPK yesterday. My test line was as dark as my control line so would yesterday be considered my actual peak day and not what glow says? My husband and I did have sex last night so fingers crossed! I had a miscarriage on thanksgiving so I truly hope we get our rainbow! 🙏🏽
