| Ovulation usually takes place 14 days after the beginning of your menstrual cycle. The time of ovulation within the menstrual cycle is determined by the luteal phase, which is usually 12 to 16 days long. You can calculate the time of ovulation within your cycle by subtracting the length of your luteal phase from the length of your cycle. The exact time of ovulation may vary within your cycle, because ovulation can be delayed by a number of factors such as stress, illness, diet, or increased physical activity. It would be best for you to buy a couple of OPK's and test everday of your cycle. Good luck to yah! |
