Can you get pregnant outside a fertile window?
Your “fertile window” refers to the time it’s most likely to get pregnant. In a typical menstrual cycle of 28 days, there are around six days when you’re most fertile (five days leading up to ovulation through one day afterwards).
But it’s important to keep in mind that cycle length can vary greatly from person to person, which was shown in a study conducted by Flo and the University of Adelaide. Even in people with regular cycles each month, the timing of the fertile window can be highly unpredictable as ovulation can take place on different days.
So, can you get pregnant when you’re not ovulating? The short answer is yes. It’s possible to get pregnant outside of your predicted fertile window because timing of ovulation may differ each month and sperm lives in the body for several days. Therefore, though more unlikely at some points, pregnancy can result from unprotected sex at any time during your menstrual cycle. If you want to avoid pregnancy, there’s actually no “safe” time of the month to have unprotected sex so it’s important to always use contraception.
