Tracking ovulation TTC month 6

Anyone have ways they track their ovulation beside using Glow? After 5 months of TTC and 1 chemical pregnancy (fertilized egg but no implantation) my husband and I think Glow is off on my ovulation day. I'm taking it onto my own hands, fertile window started today monday the 18th so I started sunday. All 4 tests have faint lines but they didn't show well in pictures so no ovulation yet but it's fun BDing til that day comes 😉 Baby dust to anyone TTC this month! 💑👪👶 don't mind my crazy markers it's all I could find lol
