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 assignment partly depends six-day fertile window.

When researchers asked these apps and websites to give a fertile window for a woman with a 28-day cycle, most of them reliably predicted the day of ovulation, the study found. If you have any queries with regards to exactly where and how to use assignment partly depends, you can get hold of us at our web-page. But only four provided the correct fertile window. "Before using any website or app, women need to understand that the actual fertile window consists of the day of ovulation plus the preceding five cycle days," said lead study author Dr. Robert Setton, a researcher at Weill Cornell Medicine and New York Presbyterian Hospital.
