If your cycle is 34 days long when do you ovulate?

If your menstrual cycle is 34 days long, ovulation typically occurs around 20 days after the first day of your last period. This is based on the general rule that ovulation happens about 14 days before the start of your next period. So, you would likely ovulate around day 20 of your cycle. However, individual variations can occur, so tracking other signs of ovulation can provide more accuracy.
