Understanding Ovulation can help you conceive sooner

Ovulation and getting pregnant

Ovulation – releasing an egg

Ovulation is when one of your ovaries releases an egg. And this is when you are most fertile – just before and after you ovulate. 

Your fertility window

This buzz of activity usually happens about 14 days before your next period. So if your cycle is 28 days long you will ovulate around day 14, and if it’s 30 days long you will ovulate around day 16. Your fertility window is the 2-3 days around this ovulation date. Your body also gives you lots of key signs you’re ovulating, from sore boobs to changes in your discharge.

Have lots of sex

To get pregnant, the egg must be fertilised by a sperm. So if you want to boost your chances of conceiving, having regular sex will mean there's always sperm hovering in the fallopian tubes, ready to meet the egg when it's released.

Find your ‘day one’

To work out when you ovulate, you need to pinpoint ‘day one’ of your monthly menstrual cycle.

"It’s easy to recognise day one because you bleed - even if it is very light,” says Richard Smith, Consultant Obstetrician. 

“This is when the egg starts ripening in your ovary, before being released into one of your fallopian tubes ."  

By keeping a note of ‘day one’, you can begin to keep a record of the length of your cycle and work out when you’ll be fertile in the next few months.

Varying monthly cycles and irregular periods

The average monthly cycle is around 28 days long, but some vary by four days or more either way. If your ovulation cycle is less than 21 days or more than 35, or if your menstrual cycle is pretty irregular. 

Many women with irregular periods have either long cycles (45 to 60 days) or in some cases will actually miss a period every few months. Factors in your life can also spark irregular periods such as stress, substantial weight loss or gain, illness, travel and even some medications.

Irregular periods can make it more challenging to  get pregnant (since it’s harder to pinpoint when you ovulate if your periods are irregular), but there is plenty of help out there. If you do have irregular periods it's worth talking to your doctor, who can prescribe medication to kick-start your period and regulate your cycle. 

As there is a known link between your emotions and your cycle, it's important to relax as much as possible. The less stress hormones you produce, the easier it is for your hormones to help keep your cycle on track.

Get a kit

Another great option is buying ovulation kits, which offer an accurate way to pinpoint when you are about to ovulate.
