Actually, it would be 14 days before your period begins.
Assuming you had a perfect, clockwork 28 day cycle, it be 14 days either way, which makes it confusing. For most women, you ovulate 10 - 14 days before your period begins. First day of your period is cycle day 1, so in a 28 day cycle, you would ovulate anywhere from cycle day 14 - 18. If you had a 32 day cycle, you would ovulate on between cycle days 18 and 22, etc. etc.
Of course, there are tons of things which can affect this. It's possible to have regular periods without ovulating at all as well as a host of other issues like short luteal phases.
