How To Use The Kit

After you download the Pearl App and receive your Pearl Fertility testing kit, this guide will lead you through the process of testing and monitoring your hormones.

Happy testing!

It all starts with a new cycle.

As soon as your next period starts, input the start date, so Pearl can start tracking your cycle. Pearl keeps track of your cycle; start, end and flow, to start your hormone testing journey.

As early as day 2 of your cycle, you can start tracking your hormones!

Daily testing

On Day 2 of your cycle, you can start monitoring your hormones. It’s not necessary to do this at a specific time, or at the same time every day, but:

For the best results, do this test first thing when you wake up.

1. Choose the right strip

The Pearl App informs you which strip to use each day. Your kit will either come with 2 or 3 kinds of test strips, depending on which you purchased. The pink strip tests your Luteinizing Hormone (LH) levels and the blue one tests your Follicle Stimulating Hormone (FSH). Find out more about the hormones you are testing here.

2. Use the strip

5 seconds

Your kit may include a urine catcher (scoop) or a strip holder. Dip the strip in a cup for 5 to 10 seconds (Stay under the MAX line) or expose the strips with the holder to midstream urine.

Wait 10-15 minutes

Place the strip on a flat surface. It takes 10-15 minutes to develop, so make yourself some tea or go about your morning meanwhile.

Why urine?

3. Take a picture

Don’t worry, it’s not an early morning selfie. In the app’s “Capture mode”, choose your cycle day & strip color.

Then take a picture of the strip, matching it to the layout on your screen.

That was easy!
