All you need to know about the fertile window"},"content":{"rendered":"

Did you know that there are only a few days each cycle during which you can get pregnant? Even if you’re regularly having intercourse and you and your partner keep your eggs and sperm in tip-top reproductive shape, this timeframe is limited. Sex can only result in pregnancy on the day of, and five days prior to, ovulation.<\/p>\n

Ovulation and the fertile window<\/h2>\n

Even if you’re not familar with\u00a0the term \u201cfertile window,” chances are you may be familiar (or familiar-ish) with ovulation. Ovulation is the phase of your cycle in which one of your ovaries releases an egg into a fallopian tube, where it can await the company of some\u00a0sperm for fertilization. Once released, an egg only has a lifespan of about 24 hours to be fertilized. If the egg is not fertilized, it disintegrates and instigates your next period. Even though the egg is only viable for 24 hours, sperm are able to survive inside a female body and fertilize the egg for up to five days after intercourse, so any intercourse within five days of ovulation could result in conception – hence, this window of time\u00a0is called the fertile window. However, the closer to ovulation your intercourse is, the higher the likelihood of conception will be.<\/p>\n

When is the fertile window?<\/h3>\n

The fertile window begins five days prior to ovulation, and ends the day after an egg is released. Supposing a perfectly regular 28-day menstrual cycle with ovulation at Day 14, this would mean that the fertile window lasts between Cycle Days 9-14. However, the vast majority of people\u00a0don’t have completely predictable 28-day cycles, and ovulation can occur at any point during a cycle. And many lifestyle factors, such as stress, may influence your ovulation date. This makes determining the date of ovulation, not just period, crucial for pinpointing the fertile window.<\/p>\n

Predict and identify the fertile window after ovulation<\/h3>\n

Though some individuals\u00a0may have such regular cycles that they have no trouble in determining their fertile windows, for most people, accurately predicting ovulation<\/a> is far trickier. In the past, people have relied on a number of different methods and tracked several different metrics to predict fertility, but Ovia Fertility is the first fertility tracker capable of making accurate predictions for ovulation by collecting and analyzing all of these different data points, and more:<\/p>\n
