Help! I need advice please! So FF has detected my ovulation as cd16. The problem with that is- I tested three times that day with OPKs and none of them were close to positive. Should I trust my chart on FF or keep testing for ovulation and ignore it’s prediction? I’m so confused! Please help 🤦🏽‍♀️🤦🏽‍♀️🤦🏽‍♀️

All of these OPKs are from the day FF says I ovulated.
