Women who turn to the internet and mobile apps to sort out the best time of the month to try getting pregnant may receive bad advice, a study suggests.

Researchers tested 20 websites and 33 apps designed to help predict what’s known as the fertile window, the days before ovulation when having sex is most likely to result in conception.

Typically, a woman with a standard 28-day menstrual cycle will ovulate around day 15, which would also be the last day of a six-day fertile window.
