Hormone-free method of contraception with no side effects

Persona is a method of natural contraception. It tracks the levels of 2 hormones in your urine to show you the days where you have to abstain from sex to avoid pregnancy. There are no side effects to worry about and you don't have to interrupt sex.

What do other people think?


"When I started having sexual relations, first thing I did is to look for the most appropriate contraception method. I didn’t had a lot of experience at that time, so was experiencing with condoms. Because of some unexpected accidents (condoms were breaking) I started off on the pill. Although it gave me headaches and made me put on weight I stuck with it for years. Then I had an implant fitted but that gave me crazy mood swings. Now my boyfriend and I use the Clearblue Contraception Monitor. I love the lack of side effects – such a relief. Would recommend for sure."


"Choosing the right contraceptive as a couple was a big decision for us. Anything I tried that contained hormones gave me side effects like headache, bloating and spots. My husband and I found barrier methods ruined any spontaneity so Persona is perfect for us. It’s easy to use and interesting for both of us to be more aware of my cycles – I used to think all women ovulated on day 14! Not the case for me at all!"

Frequently asked questions

  • 1. Do I really have to abstain from sex on all 'red' days?

    For Persona to be 94% reliable*, you must not have sex on any red days. If you choose to have sex on a red day using an alternative method, the reliability is based on the method of contraception you choose to use, and not on Persona.

    * No method of contraception can provide 100% protection against pregnancy. The Persona is 94% reliable if you follow the instructions properly and use it as the only method of contraception. This means that if 100 women use Persona for one year, we expect 6 will become pregnant because they have had sex on a day when the monitor incorrectly showed they were not at risk of becoming pregnant (green day). For the Persona to be 94% reliable, you must not have sex on red days. You are much more likely to become pregnant if you have sex on a red day, even if you use a barrier method of contraception, such as a condom.

  • 2. What if my first urine of the day isn’t within my testing window?

    If you work shifts that change your waking times, or you get up in the night to go to the toilet, you may need to collect urine to test during your testing window. Collect your urine in a clean, dry container, and store at room temperature until you are ready to test. When you are ready to test, dip the absorbent sampler into the sample for 15 seconds (not 3 seconds).

    Always test using the first urine after your longest sleep.

  • 3. What happens if I’m ill during a cycle?

    If you are able to, you should continue to use your monitor and do all the tests when your monitor asks you to. If you cannot test, your monitor will make a decision based on the information it has stored. This may mean you have more red days for that cycle and your next few cycles.

  • 4. What if I forget to look at Persona and miss a test?

    If you don’t test when asked, the monitor will usually show a red day at the end of your testing window and you may have more 'red' days than usual during that and subsequent cycles. If you have an extra Persona test stick left over at the end of your cycle, throw it away. All Persona test sticks used in a cycle must come from the same batch number.

  • 5. Can the Persona monitor lose my information?

    The monitor retains several months of your most recent cycle data. However, the monitor depends on a constant supply of battery power to keep the internal clock accurate, so you must always replace the batteries within four weeks of the battery symbol appearing. We recommend Duracell AAA long-life alkaline batteries.
