The predictions for fertile days in Clue Conceive mode are more reliable and accurate than the fertile window estimation in Clue Period Tracking mode.
Clue Conceive is based on a technology which has been clinically determined to be effective in identifying the days with the highest likelihood of conception in a person’s cycle. The technology’s algorithm, called DOT (Dynamic Optimal Timing), was tested by researchers at the Institute for Reproductive Health at Georgetown University (IRH).
In comparison, the fertile window in Clue Period Tracking mode is an estimation based on scientific literature that didn’t account for cycle variation and wasn’t backed by clinical evidence. It was never tested in a research study and therefore the prediction may not be as accurate. It was originally created to help people using Clue learn more about their body and the menstrual cycle, rather than to help them conceive.
It’s important to remember that neither Clue Conceive or Clue Period Tracking modes are effective in preventing pregnancy. Using these modes as a type of birth control may put you at higher risk of unintended pregnancy.
