can you ovulate a few days before your period
You are at your most fertile the day you ovulate and the day before (generally 12-16 days before your next period starts). So if you have a short cycle, say 20 days, it's likely you'll ovulate well before day 14, and likewise if your cycle is long, say 35 days, you are more likely to ovulate around day 20. So the 'day 14' rule is a 'textbook truth' â for those women whose cycles match the textbook idea of 28 days every time!
