Ovulation is the phase of the monthly cycle, in which ovarian follicles release a mature egg in the oviduct. This starts during the phase called Luteal Phase and the egg in the oviduct becomes ready to be fertilized by the sperm. If no fertilization happens, in a few days starts the menstruation. Ovulation starts in the middle of the menstrual cycle (on the 14th day on average). The several days before and after ovulation, from day 10 to day 18 of an average 28 days cycle, are the most appropriate for conception. This is why these days are the most important ones for one to conceive.
Using this calculator, you will be able to determine the most probable date of your ovulation. You just need to enter some basic information about your menstrual cycle as:
* the date of your last menstruation.
* the duration of your luteal phase in days – this is the time between your ovulation and when your period starts. Usually it is from 14 to 16 days long. Leave this blank, if you don’t know what to write.
* your cycles’ average length. If you are not very sure about that, please leave this blank to use the default value of 28 days (average cycle).
