Online Fertility Calculator

Calculate your chances of getting pregnant!

DuoFertility's team of in-house fertility experts have developed an easy-to-use fertility calculator to help you to calculate your chances of getting pregnant this month. All you have to do is answer a few questions about yourself, your partner and your lifestyles and the DuoFertility fertility calculator will tell you your chances of getting pregnant this month, and how this compares to other women of your age.

How It Works

The information which you enter into the conception calculator is cleverly analysed according to well-researched medical statistics and models, in order to estimate your chances of conception this month. The results of these calculations are then used to calculate your probability of conception each month into the future, in order to estimate the month(s) over which you and your partner have a 50/50 chance of achieving pregnancy. You therefore have a 1 in 4 chance of achieving pregnancy before the calculated time, a 50/50 chance within the calculated time, and a 1 in 4 chance after the calculated time.

In using a very limited range of information about your personal situation, that this calculator should only be used as a rough guide.
