When does ovulation happen? Regardless of how long or short your cycle normally is, ovulation usually occurs about 14 days before your next period starts (FPA 2014, NHS Choices 2016a). For example, say you have a regular 28-day menstrual cycle. Count the first day of your last period as day one. Your fertile window is likely to be around days 10 to 15. However, a lot of women have an irregular cycle. If this applies to you, the time from the first day of your last period to ovulation can vary from one month to the next (FPA 2014). What are the signs of ovulation? You can start to notice signs that youâre fertile about five days before you ovulate.
