Hey!
Most women, but not necessary have menstrual cycle long 28 to 30 day, some have shorter, some little bit longer, depends on every woman. Most women have, consequently, ovulation (days when woman is most fertile or when is the biggest chance woman gets pregnent) on her 14th day. But these days vary, usually form 8th to 14th day. If you wan to know adequately, you should know the adequate dates when you have periods, and then you could calculate this with your doctor, actually gynecologist.
