Clearblue Fertility Monitor — Touch Screen Ovulation Tracker

Timing is everything when you're trying to conceive — and guessing at your fertile window can feel like one more thing to get wrong. A fertility monitor takes some of that guesswork off your plate by reading your hormones instead of the calendar. Knowing your most fertile days with a little more certainty can make each cycle feel a fraction less overwhelming.

Description

The Clearblue Fertility Monitor is a touch-screen fertility monitor that reads two of your body's key hormones — estrogen and luteinizing hormone (LH) — from simple urine tests, then shows your daily fertility status as Low, High, or Peak. Because it tracks two hormones instead of one, it typically identifies more fertile days than an LH-only ovulation test — up to six in a cycle — which gives you more chances to time things well.

It stores up to six cycles of your information on a single cycle-summary screen, so you can spot patterns over time and share them with your provider. You log your period and the days you have sex right on the monitor, and it tells you which days to test. Clearblue describes it as their #1 OB-GYN recommended ovulation brand, and reports up to 97% agreement with ultrasound-confirmed ovulation and 99% accuracy at detecting the LH surge.

A few honest notes, because they matter. The monitor needs Clearblue test sticks, which are sold separately and are an ongoing cost — worth budgeting for before you buy. It's designed for cycles between 21 and 42 days, and it isn't a contraceptive. No device can guarantee a pregnancy; what this one does is give you clearer information about your timing. And if you've recently been pregnant, Clearblue advises waiting until you've had two natural cycles before using it, since lingering hCG can affect the readings.

FAQs

How does the Clearblue Fertility Monitor work?

The Clearblue Fertility Monitor reads your hormone levels to tell you when you're most fertile. It uses simple urine tests to track two hormones — estrogen and luteinizing hormone — and displays your daily status as Low, High, or Peak. Tracking both hormones lets it flag more of your fertile days than tests that read LH alone.

Does the Clearblue Fertility Monitor come with test sticks?

No. The monitor and the test sticks are sold separately, and the sticks are an ongoing cost you'll repurchase each cycle. It's worth factoring that into your budget before buying. The monitor itself is reusable and stores up to six cycles of your data, so the recurring expense is the sticks, not the device.

How is a fertility monitor different from an ovulation predictor kit?

Most ovulation predictor kits track one hormone, the LH surge, which flags roughly two fertile days. This fertility monitor tracks two hormones — estrogen and LH — so it typically identifies more fertile days, up to six per cycle. That wider window gives you more opportunities to time intercourse during each cycle.

Will a fertility monitor guarantee I get pregnant?

No. No product can guarantee pregnancy. A fertility monitor identifies your fertile window so you can time intercourse, but conception depends on many factors. If you're under 35 and have been trying for over a year, or 35-plus and trying for over six months, it's worth talking with your doctor about next steps.

Can I use it right after a miscarriage or pregnancy?

Clearblue advises waiting until you've had two natural cycles in a row before using the monitor, because hCG lingering in your body after any pregnancy can affect the readings. If you're navigating loss or a recent birth, check with your provider about when it makes sense to start tracking again.

What cycle lengths does the monitor work for?

It's designed for women whose natural cycles last between 21 and 42 days. If your cycles are very irregular or fall outside that range, the monitor may be less reliable for you, and a different approach to tracking might fit better. Your provider can help you choose the right tool for your situation.

Is this a good gift for someone trying to conceive?

It can be, for someone early in the journey who's mentioned wanting to track ovulation — it's a practical, supportive gift. Just keep in mind the test sticks are a separate, ongoing cost, so you might pair it with a pack of sticks. And because TTC can be tender, a low-pressure note tends to land best.
