To increase your chances of getting pregnant, you need to find out when you're likely to ovulate. You are most likely to be fertile during the days when your ovaries release an egg which is ready for fertilization.
Enter the first day of your last menstrual period and the average number of days in your cycle. The calculator shows you your approximate date of ovulation and assumes a regular menstrual cycle.
While predicting your fertile period can help improve your odds of getting pregnant, you should also pay attention to other cyclic factors affecting conception, such as basal body temperature and cervical mucus. Moreover, if your menstrual cycle is irregular, you may have trouble in pinpointing your ovulation time with the ovulation calculator.
Note: Estimating your ovulation date is not an effective birth control method. Do not use this for contraceptive purposes.
