It usually lasts about 14 days and does not vary by more than a day in each person. | (Default: 14) |

The ovulation calendar allows you to effectively predict when you are most
fertile each month. You can use the calendar to try and increase your chances
on falling pregnant as well as understand when the optimal time to take a
pregnancy test is. Simply let us know when the first day of your last menstrual cycle was as well as how long your cycle and luteal phase lasts and then we can do the rest! If you don't know the length of either your menstrual cycle or luteal phase then you can leave these as the average value of 28 and 14 respectively. However, we recommend that you record these as it can help predict more accurately your ovulation dates. Please note, that the dates given in ovulation calendar are based on a regular menstrual cycle. If your cycle is irregular this may not be the most accurate way to work out when you are ovulating. |
