Ovulation Testing Kits

Find the best clinic for you


To determine when you are most fertile each month, the best indicator is to use an ovualation testing kit.

Ovulation predictor kits

These can be over the counter in most pharmacies and drugstore chains. They work by measuring the amount of luteinising hormone (LH) in urine and are around 90% accurate.

Saliva microscopes

These, as the name suggests, are small microscopes, which allow you to examine your saliva. As estrogen levels build up as you head toward ovulation, salt levels in your saliva increase. When you look at the saliva under a microscope, the salt causes a pattern that’s like the leaves of a fern plant. The problem here is that other things may cause your salivary salt levels to fluctuate – not just estrogen levels.

Cervical mucus

Learning how to spot changes in your cervical mucus is an easy way to try and predict when you ovulate. It is not foolproof but can be used in conjunction with any of the other methods to improve the confidence of prediction.

Core body temperature

Checking your core body temperature is a way to predict when you ovulate and it has helped women get pregnant. During ovulation, your body releases the hormone progesterone. Within a day or two this causes a slightly raised temperature, by about 0.5 degrees Celsius a day or two later. Normally the temperature then stays at the higher until the next cycle begins. And if you become pregnant during that cycle, your temperature will stay up beyond that.

That half of a degree difference may not seem like much, but it is crucial. Therefore, it is ESSENTIAL that the temperature readings are accurate.

OvuFirst™ is targeted at women who wish to monitor their ovulation and cycles in a convenient, non-invasive way by wearing the clinically-proven sensor on the arm or wrist overnight.




In a normal cycle, you will ovulate in the middle of your cycle, so if you have a 28-day cycle then this would be on day 14. The first day of your period is counted as day 1 of your cycle. Whatever the length of your cycle, just work out the middle day for ovulation.

If you think you are having a problem ovulating then you should consult a fertility specialist for more investigations.
