It can be a challenging time if you're struggling to conceive, but try not to worry - they say stress can make it harder to fall pregnant! Instead give yourself the best chance by cluing yourself up with our ovulation calculator.
An ovulation calculator can be super helpful if you’re trying to get pregnant. Knowing when you’re ovulating can seem a bit confusing, especially if your periods aren’t regular. To stand your best chance of conceiving, you should try using an ovulation calculator.
It’s important to know when the best time to try for a baby is. If you work out when you’re most fertile, you can schedule in some time to get steamy!
An average woman’s menstrual cycle is 28 days but cycles can range from 22 days right up to 36 so don’t just guess. Your menstrual cycle begins on the first day of your period and continues up to the day before you start your next one.
Along with your average menstrual cycle length, you will also need to know the length of your ‘luteal phase’ to use our ovulation calculator as efficiently as possible. The luteal phase begins after ovulation and ends the day before your next period. It usually lasts 12 to 16 days, with an average of 14 days for most women, so if you’re unsure we’d recommend choosing 14 days on the calculator.

Alternatively, follow these three steps to calculate your ovulation date and find out when you’re likely to be most fertile.
Step 1: Your menstrual cycle
When your next period starts, make a note of the date. The following month, when your period comes again, make a note of this date, then count the days in between. This will give you your cycle length. You may need to do this for more than one month and take the average, especially if your cycle isn’t regular. Remember also that coming off the Pill will reveal your true menstrual cycle.
Period starts = 1st January Next period starts = 3rd February
Days in between (including 1st Jan but not 3rd Feb) = 33 days.
Your menstrual cycle length is 33.
Step 2: Your fertile dates
Using our ovulation calendar, find the right number in the menstrual cycle length column (33 for the above example) and read across for your ovulation day and most fertile days.
|Cycle length||Ovulation||Most fertile|
|22||Day 8||Days 7-9|
|23||Day 9||Days 8-10|
|24||Day 10||Days 9-11|
|25||Day 11||Days 10-12|
|26||Day 12||Days 11-13|
|27||Day 13||Days 12-14|
|28||Day 14||Days 13-15|
|29||Day 15||Days 14-16|
|30||Day 16||Days 15-17|
|31||Day 17||Days 16-18|
|32||Day 18||Days 17-19|
|33||Day 19||Days 18-20|
|34||Day 20||Days 19-21|
|35||Day 21||Days 20-22|
|36||Day 22||Days 21-23|
Step 3: Your ovulation date
Work out your ovulation and most fertile dates. For the below example:
First day of last period = 3rd February 2008
Cycle Length = 33
Ovulation (19 days later) = 22nd February 2008
Most fertile (18-20 days later) = 21st and 23rd February 2008
