Taking conception to the next level, the Clearblue® Fertility Monitor maximizes a woman’s chances of conceiving a baby by identifying 3x more fertile days compared to traditional ovulation tests. The #1 brand recommended by OB/GYNs, this electronic, hand-held monitor tracks a woman’s personal cycle, detecting two key ovulation hormones: luteinizing hormone (LH) and estrogen. Using the two hormones, the device can pinpoint not only a woman’s 2 peak fertility days, but also 1-5 additional high fertility days prior to ovulation – for a total of up to 6 fertile days.
There are only a few days per cycle when a woman is fertile and can conceive. The following chart outlines the phases of a woman’s menstrual cycle, showing how the two most fertile days coincide with the LH surge (24-36 hours before ovulation) and the release of an egg (ovulation). These are a woman’s 2 best days to conceive a baby.
However, it is generally acknowledged that sperm can survive up to 5 days in the sperm-supportive mucus found in a woman’s body during the fertile days of her cycle meaning there is a fertile window of typically up to 6 days: 5 days before ovulation plus the day of ovulation. Traditional ovulation tests like Clearblue Digital Ovulation Test track the LH hormone and identify a 2 day window of fertility. But the Fertility Monitor also tracks estrogen levels, which rise just before the LH surge, extending the fertile window typically up to 6 days. This extended window can help to reduce the time it takes to conceive2 as it gives more days to try, plus gives advance notice of the 2 peak days.
The Fertility Monitor is easy to use and gives you clear accurate results.
Low fertility = very small chance of conceiving
High fertility = increased chance of conceiving
Peak fertility = highest chance of conceiving
When you’re ready to test for pregnancy, choose a brand and product you can trust. In the Clearblue Pregnancy Test Buying Guide, we outline the different features of pregnancy tests so you can feel maximum confidence throughout the entire conception process.
As the diagram above illustrates, timing is key when trying to conceive a baby. While there are manual charting and calculator methods that may be used to predict ovulation, these methods often fall short. They require tracking a woman’s typical cycle length over several months. However, every woman’s cycle is unique and cycles for any one woman can vary from cycle to cycle – making calendar-based predictions unreliable prediction as well as time-consuming. That’s why Clearblue provides a range of products to help predict ovulation without months of charting. You can learn more about predicting ovulation and which method is right for you in our Ovulation Test Buying Guide.
